My Teen Is Cutting: Understanding Self-Harm and How to Help

Crisis Guide • Adolescent Self-Harm • Last updated March 2026

You found the marks on their arms. Or their thighs, or their stomach — places they've been hiding under long sleeves and excuses. Maybe you saw blood on a towel, or found a razor blade in their room, or their friend's parent called you. However you discovered it, finding out your teenager is deliberately hurting themselves is one of the most shocking and frightening experiences a parent can have.

Your first instinct might be panic, anger, confusion, or all three. You might want to demand they stop, confiscate everything sharp in the house, or rush them to the emergency room. Before you act, take a breath and read this guide. How you respond in this moment matters — it will determine whether your teen opens up or shuts down, and whether they get the help they need.^[1]

Why Teens Self-Harm

The most important thing to understand: self-harm is almost always a coping mechanism, not a suicide attempt. Teens who cut or otherwise hurt themselves are typically trying to manage overwhelming emotions — not end their lives. This distinction matters because it changes how you respond.

Emotional regulation

The most common reason teens give for self-harm is that it provides relief from intense emotional pain. When emotions become unbearable — rage, sadness, anxiety, shame, numbness — physical pain can feel like a release valve. The body's pain response triggers endorphins, providing a brief biochemical shift that temporarily alleviates emotional suffering. The teen isn't choosing self-harm because they're "crazy" — they're choosing it because, in that moment, it's the only coping mechanism that works for them.

Feeling something when numb

Some teens describe feeling emotionally dead, disconnected from themselves and the world. Physical pain cuts through the dissociation and makes them feel real again. This is particularly common in teens with trauma histories or depressive disorders.

Self-punishment

Teens with intense shame, self-hatred, or guilt may use self-harm as a form of punishment. They believe they deserve to hurt. This is especially common in teens who have experienced abuse, bullying, or who have developed deeply negative self-concepts.

Communication of distress

Some teens self-harm because they cannot find words for what they're feeling. The visible injury communicates the invisible pain. This is not the same as "attention-seeking" — a label that should be retired from the conversation about self-harm. A teen who is using self-harm to communicate distress is telling you they need help in the only language they have available.

Control

In a life that feels chaotic or controlled by others, self-harm can feel like one of the few things the teen controls. They choose when, where, and how much — which can feel empowering in a world where everything else feels out of their hands.^[2]

Forms of Self-Harm Beyond Cutting

Cutting is the most recognized form of adolescent self-harm, but it's not the only one. Parents should be aware that self-harm also includes:

• Burning — with cigarettes, lighters, matches, or friction burns from erasers ("eraser challenges")
• Scratching or picking — deep scratching with fingernails or picking at wounds to prevent healing
• Hitting or punching — walls, hard surfaces, or their own body
• Hair pulling (trichotillomania) — pulling hair from the scalp, eyebrows, or other areas
• Ingesting harmful substances — swallowing objects, consuming small amounts of toxic substances, or intentional minor overdoses
• Interfering with wound healing — reopening cuts, removing stitches, picking scabs deliberately
• Excessive exercise as self-punishment — particularly in the context of eating disorders

How to Spot the Signs

Teens who self-harm typically go to significant lengths to hide it. Warning signs include:

• Wearing long sleeves and pants in warm weather, or refusing to change clothes for activities that would expose skin (swimming, sports)
• Unexplained cuts, burns, bruises, or scars — especially in patterns or on areas typically covered by clothing (upper arms, thighs, stomach, chest)
• Frequent "accidents" to explain injuries — "the cat scratched me," "I fell"
• Blood stains on clothing, towels, or bedding
• Finding razors, blades, lighters, or sharp objects in their room or belongings that don't have an obvious purpose
• Spending long periods alone in the bathroom or bedroom, especially after emotional episodes
• Increased secrecy about their body — locking doors, reacting strongly to physical closeness
• Withdrawal from friends and activities, declining mood, or increased emotional volatility

Self-Harm vs. Suicide: Understanding the Difference

Self-harm and suicide are related but distinct behaviors. Most teens who self-harm are not trying to die — they are trying to cope with living. However, this distinction does not mean self-harm is "safe" or should be dismissed:

• Self-harm increases suicide risk. A teen who self-harms is significantly more likely to attempt suicide than a teen who doesn't, even if the self-harm itself is not suicidal in intent. Self-harm may escalate in severity over time, and accidental fatal injury can occur.^[3]
• Self-harm and suicidal ideation can coexist. A teen can engage in self-harm for emotional regulation purposes while also having thoughts of suicide. Don't assume one excludes the other.
• Always assess for suicidal thoughts. When you discover self-harm, asking about suicide directly is essential. See our guide on how to talk to your teen about suicide.

How to Respond When You Find Out

What to do

• Stay calm. Your teen is watching your reaction. If you panic, rage, or cry uncontrollably, they will learn that their self-harm is too much for you to handle — and they'll hide it better next time instead of getting help.
• Express care, not horror. "I love you and I can see you're in a lot of pain. I want to help you find better ways to cope with this."
• Ask questions and listen. "Can you help me understand what you're going through? I'm not going to judge you — I just want to understand." Then actually listen without interrupting or problem-solving.
• Attend to any injuries. If there are open wounds, provide first aid. If wounds appear deep or infected, seek medical attention.
• Get professional help. Self-harm is a clinical issue that requires professional treatment. Schedule an evaluation with a therapist or psychiatrist who specializes in adolescent self-harm. This is not something that willpower, punishment, or conversations alone will resolve.

What not to do

• Don't make them show you. Demanding to see their injuries feels invasive and shaming. A clinician can assess the physical damage.
• Don't issue ultimatums. "Stop cutting or I'm taking your phone" treats self-harm as a behavioral choice rather than a symptom of deeper distress. It drives the behavior underground.
• Don't remove all sharp objects in a panicked sweep. While reasonable safety measures are appropriate (see below), dramatically stripping the house of everything sharp communicates that your teen's problem is too terrifying and overwhelming, and it rarely prevents self-harm — teens who are determined will find other methods.
• Don't punish. Self-harm is not defiance. Grounding, taking away privileges, or expressing anger as a response to self-harm ensures your teen will never tell you when they're struggling.
• Don't ignore it. Some parents, overwhelmed by the discovery, minimize or avoid addressing it, hoping it will stop on its own. It usually doesn't. The average duration of self-harm behavior before a teen receives treatment is over a year.

Treatment That Works

Dialectical behavior therapy (DBT)

DBT is the treatment with the strongest evidence base for self-harm in adolescents. Originally developed for adults with borderline personality disorder and chronic suicidality, DBT has been adapted for teens (DBT-A) and specifically targets the emotional dysregulation that drives self-harm. It teaches four core skill sets: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. DBT-A typically includes individual therapy, a skills group, and family involvement.^[4]

Cognitive behavioral therapy (CBT)

CBT helps teens identify the thoughts and emotions that precede self-harm episodes and develop alternative coping strategies. While CBT has a strong evidence base for depression and anxiety (which often co-occur with self-harm), DBT is generally preferred when self-harm is the primary concern.

Mentalization-based treatment (MBT)

MBT helps teens understand their own and others' mental states — thoughts, feelings, motivations. Many teens who self-harm have difficulty identifying and articulating what they're feeling, and MBT directly addresses this deficit.

Family therapy

Because self-harm affects the entire family and family dynamics can inadvertently maintain the behavior, family therapy is often an important component. Parents need to learn how to respond to self-harm without either accommodating it or punishing it, and siblings need support processing their own reactions. See our guide on family therapy explained.

Medication

There is no medication specifically for self-harm. However, if self-harm co-occurs with depression, anxiety, PTSD, or another diagnosable condition (which it usually does), medication for the underlying condition may reduce the emotional distress driving the self-harm. See our medications guide.

Higher levels of care

If self-harm is severe, escalating, or accompanied by suicidal ideation, a higher level of care may be necessary. IOP, PHP, or residential treatment can provide the intensive support needed to break the cycle. See our levels of care guide and treatment duration guide.

Making Home Safer

A measured approach to reducing access to self-harm implements is appropriate — not a panicked purge, but a thoughtful reduction of risk:

• Lock up medications (prescription and over-the-counter) in a secure location
• Store sharp objects (razors, craft knives, box cutters) in a locked container — discuss this openly with your teen rather than doing it secretly
• Keep a well-stocked first aid kit accessible so that if self-harm does occur, your teen can care for wounds rather than hiding them
• Create a "crisis kit" with your teen — items that provide sensory alternatives to self-harm: ice cubes (intense cold without injury), red markers (visual simulation), rubber bands (mild snap without lasting harm), strong mints or hot sauce (intense sensation), a stress ball, journaling materials
• Develop a safety plan with your teen's therapist — a written document listing warning signs, coping strategies, people to contact, and emergency resources

Self-Harm and Social Contagion

Research shows that self-harm can spread through social networks — if one teen in a friend group self-harms, others are at increased risk. Online communities can also normalize and even encourage self-harm, with some social media spaces sharing methods, glorifying scars, or creating competitive dynamics around injury severity.^[5]

This doesn't mean your teen is self-harming "because their friends do it" — the emotional distress driving the behavior is real. But peer influence can shape how that distress is expressed. If you're aware that your teen's social circle includes others who self-harm, this is important information for the treatment team.

Monitor your teen's online activity for involvement in self-harm communities, but do so openly rather than secretly. "I need to check in on what you're seeing online because some of this content can make things harder" is more effective than covert surveillance, which damages trust. See our guide on social media and teen mental health.
