Understanding Self-Harm: A Guide for Families and Friends

Self-harm is a behavior that many people find difficult to understand, and discovering that someone you love is hurting themselves can bring up a flood of emotions—fear, confusion, guilt, and even anger. It is common among adolescents and young adults, but it can affect people of any age. At its core, self-harm is usually a sign of deep emotional pain, not a cry for attention or a phase to be outgrown. It is often linked to mental health conditions such as depression, anxiety, post-traumatic stress disorder (PTSD), or borderline personality disorder. For families and friends, learning how to respond with empathy instead of panic can make a real difference. This guide provides a thorough look at what self-harm is, what drives it, how to recognize it, and how to offer meaningful support to someone you care about.

If you are reading this because you are worried about a loved one, know that you are taking an important step. Self-harm is not a life sentence, and with the right support and treatment, recovery is possible. Your willingness to learn and stay present matters more than you might realize.

What Is Self-Harm?

Self-harm, clinically referred to as nonsuicidal self-injury (NSSI), is the deliberate, direct destruction of one’s own body tissue without the intent to die. The most common forms include cutting, scratching, burning, hitting, biting, or interfering with wound healing. Some individuals may also engage in hair pulling (trichotillomania) or skin picking to the point of injury, though these behaviors can have distinct clinical features.

It is important to distinguish self-harm from suicidal behavior. While the two can co-occur, most people who self-harm do so as a way to cope with overwhelming emotional states, not as an attempt to end their lives. In fact, many describe self-harm as a survival strategy—a way to release pressure, feel something when they feel numb, or regain a sense of control when life feels chaotic.

Research suggests that between 15% and 20% of adolescents will engage in self-harm at some point, and rates among young adults are also significant. These numbers are likely underestimated because self-harm is often hidden due to shame. It is not a rare or fringe behavior—it is a common response to uncommon levels of distress.

Common Misconceptions About Self-Harm

Many myths surround self-harm, and they can get in the way of compassionate support. One of the most damaging is the belief that self-harm is simply “attention-seeking.” In reality, most individuals go to great lengths to hide their injuries, wearing long sleeves even in hot weather and making excuses for cuts and bruises. Another misconception is that self-harm is a manipulative tactic meant to control others. Again, the evidence points the other way: self-harm is typically a private, shame-filled act, not a performance.

Understanding these nuances is critical. When families and friends respond from a place of accurate knowledge, they are less likely to react with blame or judgment, and more likely to create a safe space for healing.

Why People Self-Harm: Understanding the Root Causes

Every person’s experience with self-harm is unique, but several common psychological drivers emerge across cases. Recognizing these can help you respond with empathy rather than frustration.

Emotional Regulation and Distress Tolerance

For many, self-harm is a way to manage emotions that feel too big to handle. Intense anger, sadness, anxiety, or even a sense of emotional numbness can become unbearable. The physical pain of self-injury releases endorphins, which can produce a temporary sense of relief or calm. Over time, this relief becomes a learned coping mechanism—a shortcut to feeling better, even though it comes with serious costs.

Self-Punishment and Shame

People who struggle with low self-esteem, perfectionism, or deep-seated shame may harm themselves as a form of punishment. They may believe they deserve to hurt because of perceived failures, mistakes, or flaws. This pattern is especially common in individuals who have experienced trauma or who grew up in environments where they were harshly criticized or punished.

Control and Agency

When life feels unpredictable or overwhelming, self-harm can provide a sense of control over at least one thing: one’s own body. The ability to choose when and how to experience pain can feel empowering in a context where everything else feels chaotic. This is particularly relevant for those who have experienced abuse or neglect, where their sense of autonomy was violated.

Communication and Expression

Some individuals struggle to put their internal experience into words. For them, self-harm can be a way to communicate distress that feels otherwise unspeakable. It can be a way of saying, “I am hurting this much,” when language fails. This is not manipulation—it is a desperate attempt to be seen and understood.

Distraction from Emotional Pain

The physical sensation of pain can serve as a powerful distraction from emotional anguish. For someone drowning in intrusive thoughts, memories, or feelings, focusing on a physical injury can offer temporary relief. It is a way to shift attention from the internal to the external.

Understanding these drivers can help families and friends move past the question “Why would they do that?” and toward “What must they be feeling to need this?”

Recognizing the Signs of Self-Harm

Self-harm is often hidden, but there are signs you can watch for. Being observant without being invasive is key. The goal is not to spy, but to notice patterns that may indicate suffering.

Physical Signs

  • Unexplained cuts, burns, bruises, or scars, particularly on the arms, wrists, thighs, stomach, or chest
  • Frequent use of bandages, gauze, or medical tape without a clear reason
  • Wearing long sleeves, long pants, or wristbands even in hot weather or during activities where they would be unusual
  • Excuses for injuries that sound vague or inconsistent, such as “I got caught on a fence” or “the cat scratched me”

Behavioral and Emotional Changes

  • Withdrawal from friends, family, or activities they used to enjoy
  • Spending increasing amounts of time alone, especially in bedrooms or bathrooms
  • Irritability, mood swings, or sudden outbursts of anger or crying
  • Expressions of hopelessness, worthlessness, or self-hatred
  • Declining performance at school or work
  • Changes in sleep or eating patterns

Hidden Objects

You may notice sharp objects like razors, knives, scissors, or broken glass in places where they don’t belong. Lighters or matches may also appear, even if the person does not smoke. Finding such items does not automatically mean self-harm, but it is worth paying attention to in combination with other signs.

If you notice several of these signs, it is appropriate to express concern. Avoid accusations. Instead, focus on the changes you’ve observed and your care for the person.

How to Talk About Self-Harm

Starting a conversation about self-harm can feel intimidating, but silence can make things worse. When done carefully, a conversation can reduce shame and open the door to help.

Choose the Right Moment

Find a private, quiet time when you are both calm. Do not start the conversation right after discovering an injury or during an argument. You want to create a space where the person feels safe enough to be honest.

Use a Gentle Opening

Instead of confronting with “I know you’re hurting yourself,” try something like: “I’ve noticed you seem really down lately, and I’m worried about you. I want to understand what’s going on and how I can help.” This approach is less likely to provoke defensiveness and more likely to invite trust.

Listen Without Judgment

If the person opens up, your most important job is to listen. Do not interrupt, correct, or minimize their experience. Statements like “That sounds incredibly hard” or “Thank you for trusting me with this” can go a long way. Avoid saying things like “Just stop” or “You have so much to live for”—these dismiss the complexity of their pain.

Ask Directly About Safety

It is a myth that asking about self-harm or suicide will put the idea in someone’s head. In reality, asking directly can be a relief. You can say: “When you hurt yourself, were you also thinking about ending your life?” This question helps you understand the level of risk and whether immediate professional help is needed.

Offer Reassurance

Let the person know they are not a burden and that you are there for them. Say things like: “I’m not going to leave you alone in this. We will figure this out together.” Consistency matters. Follow up on what you say.

Myths vs. Facts About Self-Harm

Correcting misinformation is essential for providing the right kind of support. Here are some of the most common myths and the facts that counter them:

  • Myth: People who self-harm are just trying to get attention.
    Fact: Most people who self-harm do so in secret and feel deep shame about it. They are not seeking an audience—they are trying to cope.
  • Myth: Self-harm always leads to suicide.
    Fact: Many people use self-harm as a way to avoid suicide—to manage pain without ending their lives. However, self-harm is a risk factor for suicidal thinking, so professional evaluation is always warranted.
  • Myth: Only teenagers self-harm.
    Fact: While self-harm is more common in adolescents, it affects adults as well, often as part of ongoing mental health struggles like depression, PTSD, or personality disorders.
  • Myth: If the injuries are minor, it is not serious.
    Fact: The severity of self-harm is not measured by the depth of a cut or the size of a burn. It is measured by the emotional distress behind the act. All self-harm deserves a compassionate response.
  • Myth: Self-harm is a phase that people grow out of.
    Fact: While some do stop on their own, many continue unless they receive appropriate support and treatment. It is not something to simply “wait out.”

Supporting Someone Who Self-Harms

Your role as a family member or friend is to be a steady, nonjudgmental presence. You do not need to be a therapist—you just need to be a caring human being.

Encourage Professional Help

Self-harm is a symptom of deeper distress, and that distress often requires professional attention. Gently suggest speaking with a therapist, especially one trained in dialectical behavior therapy (DBT) or cognitive-behavioral therapy (CBT). Offer to help find a provider or to accompany them to the first appointment. If cost is a barrier, look into community mental health centers or sliding-scale clinics.

Work on Coping Strategies Together

It can be helpful to create a list of alternative coping strategies that the person can try when the urge to self-harm arises. These might include: holding ice cubes, drawing on the skin with a red marker, snapping a rubber band on the wrist, running cold water over hands, writing in a journal, doing a breathing exercise, or calling a trusted friend. Not every strategy will work for everyone, but having options is better than having none.

Remove Immediate Means

With the person’s consent, you can help remove objects used for self-harm from their environment, especially during high-risk periods. This is not about taking away control—it is about creating a safer space for recovery. If the person is not ready to let go of these items, respect their pace while continuing to offer support.

Check In Regularly

Small, consistent gestures of care can reduce isolation. A simple text saying “Thinking of you” or “How are you doing today?” can remind the person that they are not alone. Avoid pressure—let them respond at their own pace.

Be Patient with Setbacks

Recovery is rarely a straight line. There will be good days and hard days. If the person self-harms again, avoid expressions of disappointment or anger. Instead, focus on what they can learn from the experience and how to move forward. Say something like: “This happened, and we are still here. Let’s figure out what to do next.”

What to Do If You Discover Active Self-Harm

Finding someone in the middle of self-harming or with a fresh injury can be alarming, but staying calm is essential.

Stay Present and Calm

Take a breath. Do not react with shock or anger. Say something like: “I’m here with you. Let’s take care of this injury first.” Your calm presence can help de-escalate the situation.

Provide First Aid if Needed

If the injury is serious—deep cuts, heavy bleeding, signs of infection—seek medical help immediately. For minor injuries, help clean and bandage the area. Do not lecture or moralize during this moment. Focus on physical care first.

Ask About Suicidal Thoughts

As mentioned earlier, ask directly: “When you hurt yourself, were you also thinking about ending your life?” If the answer is yes, do not leave them alone and seek emergency help. If the answer is no, you can still help them connect with professional support.

Use Grounding Techniques

If the person is in emotional distress, grounding exercises can help bring them back to the present. Ask them to name five things they can see, four things they can touch, three things they can hear, two things they can smell, and one thing they can taste. This can interrupt the intensity of the emotional surge.

Call a Crisis Line if Needed

If you feel overwhelmed or if the person is at immediate risk, call a crisis line for guidance. The 988 Suicide & Crisis Lifeline is available 24/7. You can also text HOME to 741741 to reach the Crisis Text Line.

Treatment Options for Self-Harm

Self-harm is treatable, and many people recover fully with the right help. Treatment typically addresses both the behavior itself and the underlying mental health conditions driving it.

Therapy

Dialectical behavior therapy (DBT) is one of the most effective approaches for reducing self-harm. It teaches skills for emotional regulation, distress tolerance, interpersonal effectiveness, and mindfulness. Cognitive-behavioral therapy (CBT) can also be helpful, especially when self-harm is linked to depression, anxiety, or trauma. For younger individuals, family-based therapies may be recommended.

Medication

There is no medication that directly stops self-harm, but antidepressants, anti-anxiety medications, or mood stabilizers can help manage the underlying conditions that contribute to it. A psychiatrist can evaluate whether medication might be a helpful part of the treatment plan.

Support Groups

Connecting with others who have similar experiences can reduce shame and build a sense of community. Organizations like Self-Injury Outreach & Support (SIOS) offer resources and peer support. Some individuals also benefit from in-person or online support groups facilitated by mental health professionals.

Hospitalization

In acute crises where the person cannot keep themselves safe, short-term hospitalization may be necessary. This is not a punishment—it is a way to stabilize the person and keep them alive until they can engage in outpatient treatment.

Creating a Supportive Home Environment

The environment a person returns to after treatment or during recovery can have a major impact on their progress. Families and friends can take steps to make that environment more supportive.

Encourage Open Expression

Create a culture where emotions are welcome, not punished. Let your loved one know that they can talk to you about anything without fear of judgment or backlash. Use “I” statements to express concern without blame, such as “I feel worried when you pull away, and I want to make sure you know I’m here.”

Model Healthy Coping

Actions speak louder than words. When you face stress, talk about how you are handling it. Say things like: “I had a tough day, so I’m going to go for a walk to clear my head.” This normalizes the idea that everyone needs healthy outlets.

Reduce Stigma and Shame

Avoid language that frames self-harm or mental health struggles as a moral failing. Phrases like “you’re being weak” or “just snap out of it” are harmful. Instead, treat self-harm as a symptom of a health condition—something to be treated, not condemned.

Set Boundaries with Love

You can be supportive without being available at all hours. Establish clear, kind boundaries. For example: “I may not always be able to respond to texts immediately, but I will always get back to you as soon as I can. If you are in crisis, please call the crisis line.” This protects your well-being while still offering care.

Taking Care of Yourself as a Caregiver

Supporting someone who self-harms is emotionally demanding. You cannot pour from an empty cup. Taking care of yourself is not selfish—it is necessary.

Seek Your Own Support

Talk to a trusted friend, a therapist, or join a family support group. Organizations like the National Alliance on Mental Illness (NAMI) offer support groups for families, which can help you feel less alone and more equipped.

Practice Self-Care

Carve out time for activities that restore you—exercise, reading, hobbies, time in nature, or simply resting. Self-care is not a luxury; it is a requirement for sustained caregiving.

Educate Yourself

The more you understand self-harm and mental health, the less daunting it becomes. Read books, attend workshops, or take a Mental Health First Aid course. Knowledge builds confidence.

Manage Guilt and Worry

It is common to ask, “What did I do wrong?” or “Could I have prevented this?” While these questions are understandable, they are often unhelpful. Self-harm is not caused by one person or one event. Focus on what you can do now: offer support, learn, and stay present.

Set Limits on Your Role

You cannot be the only person your loved one relies on. Encourage them to build a support network that includes a therapist, school counselor, doctor, and trusted peers. This distributes the load and gives them more resources to draw from.

Long-Term Recovery and Hope

Recovery from self-harm is a process, not an event. Many people learn to replace self-injury with healthier coping skills and go on to live full, meaningful lives. Relapses can happen, and they are not failures—they are part of the learning curve. What matters most is the commitment to keep going, both for the person recovering and for those supporting them.

Celebrate the small wins: a day without self-harm, using a coping strategy during a difficult moment, reaching out for help instead of acting on an urge. Each step forward builds momentum. With professional treatment, a supportive environment, and consistent care, healing is not just possible—it is probable.

You and your loved one are not alone in this journey. Resources are available, and recovery is real. Hold on to hope, and take it one day at a time.
