What is self-injury?
Self-injury, sometimes called self-harm or nonsuicidal self-injury, means intentionally hurting your own body. Cutting is one form, but self-injury can take other forms too. The important part is the intent: the behavior is being used to cope with emotional pain, numbness, anger, shame, stress or another difficult internal experience.
Self-injury often begins during the teen or early adult years. SAMHSA and MedlinePlus both describe it as a behavior rather than a mental disorder by itself. A person who self-injures may also be dealing with depression, anxiety, trauma, eating disorders or another mental health condition.
Self-injury is not the same thing as a suicide attempt. Many people who self-injure say they are trying to manage unbearable feelings rather than die. That distinction matters, but it does not make the behavior harmless. People who self-injure are at higher risk for suicidal behavior, and any self-injury deserves attention.
Why would hurting yourself bring relief?
From the outside, self-injury can be hard to understand. Inside the experience, it may temporarily interrupt emotional overload, make numbness feel more concrete, release tension or create a sense of control. Some people use it to punish themselves. Others do not fully understand why the urge feels relieving until they begin talking about it in treatment.
The temporary relief is one reason the behavior can repeat. Your brain learns that distress was followed by an action and then a change in feeling. Treatment helps build other ways to survive the same emotional wave without adding injury, secrecy and shame afterward.
Self-injury is not “attention-seeking”
Some people hide self-injury for months or years. Others may reveal it because they desperately need someone to notice that they are not okay. Either way, dismissing the behavior as drama misses the point. If a teenager is hurting themselves or showing that they are in serious emotional pain, they need support and evaluation, not humiliation.
Signs and symptoms of self-injury
Possible signs include unexplained or repeated injuries, scars, covering the body in ways that seem unusual for the weather, frequent explanations about accidents, keeping potentially harmful objects nearby, withdrawing from others or talking about feeling worthless, hopeless or unable to cope.
No single sign proves self-injury. Some people have injuries for completely different reasons, and some people who self-injure are very careful to hide it. The larger pattern matters.
Emotional warning signs
Self-injury may happen during periods of intense anger, loneliness, shame, emptiness, conflict or feeling trapped. The urge can become stronger after arguments, bullying, breakups, academic pressure, trauma reminders or feeling rejected. For some teens, the urge seems to appear suddenly because they have not yet learned to identify the buildup.
Self-injury may also occur with PTSD or eating disorders. Treating only the injury without understanding the emotional or mental health problems underneath it can leave the main problem untouched.
Secrecy can make the cycle stronger
You may hide injuries because you are afraid adults will overreact, take away privacy, get angry or treat you differently. Those fears can be real. At the same time, secrecy can make the behavior easier to repeat because no one knows how much you are struggling.
If telling a parent or guardian feels unsafe or impossible, another trusted adult can help you figure out what to do next. A school counselor, nurse, psychologist, social worker, teacher, coach, relative or health care provider can be a starting point.
Self-injury and suicide risk
A person can self-injure without wanting to die and still later experience suicidal thoughts. That is why providers ask directly about both. If you are thinking about suicide, feeling unable to stay safe or unsure whether you might seriously harm yourself, get immediate help. Our article on suicide and suicidal thoughts explains warning signs and crisis options.
Diagnosis and tests
There is no lab test for self-injury. A health care or mental health professional evaluates what is happening by talking with you about the behavior, the feelings that come before and after it, how often it happens, whether injuries need medical treatment and whether there are thoughts of suicide.
The clinician may also evaluate for depression, anxiety, trauma, eating disorders, substance use or other conditions. This is not about collecting labels. Understanding what is driving the behavior helps build a treatment plan that actually fits.
Medical care may be needed
Injuries can cause infection, scarring or other complications. If an injury is serious, will not stop bleeding, looks infected or otherwise needs medical attention, tell an adult and get medical care. You do not have to explain your entire mental health history before an injury deserves treatment.
Expect safety questions
A provider will probably ask whether you have thoughts of suicide, whether you have made a suicide plan and whether you feel able to stay safe. Answer as honestly as you can. The purpose is not to punish you. The provider needs to understand how urgent the situation is and what level of care is safest.
School support
Self-injury itself is not an academic diagnosis, but the mental health conditions connected with it may affect attendance, concentration and functioning. A school counselor or mental health professional can help coordinate support. Depending on a student’s needs and eligibility, formal accommodations or services may also be available.
Treatment for self-injury
Treatment focuses on understanding what the behavior is doing for you and building safer ways to handle the same feelings. There is no medication specifically approved to “cure” self-injury, but medication may be used to treat depression, anxiety or another condition that is contributing to distress.
Psychotherapy
Therapy can help identify triggers, challenge shame, improve emotional regulation and practice alternatives before an urge becomes overwhelming. Different evidence-based approaches may be used depending on the person and other diagnoses. Treatment may include individual therapy, family involvement or a more intensive program when risk is high.
The goal is not simply “promise you will never do it again.” A promise does not replace skills. Good treatment helps you understand the moments when the urge is strongest and build a plan for those moments.
Safety planning
A therapist or other professional may help you create a safety plan that identifies warning signs, people to contact, places to go and steps that make it harder to act on an urge. Because teens often depend on adults for transportation, medical care and access to treatment, involving a safe adult is usually important.
If the behavior becomes life-threatening
Some people need more intensive treatment, such as a partial-hospitalization program, intensive outpatient program or inpatient care. That level of support is not a punishment. It is used when safety or severity requires more structure than ordinary outpatient appointments can provide.
Outlook
People can stop self-injuring. The urge may take time to change, especially if the behavior has become an automatic coping response. Recovery often involves setbacks, learning new skills and treating other mental health conditions at the same time.
A lapse does not erase progress. It is information about what overwhelmed the current coping plan. The safest response is to tell your treatment team or trusted adult, get medical care if needed and look at what support needs to change.
Scars can carry complicated feelings
Some people feel ashamed of scars. Others see them as evidence of a period they survived. You do not owe anyone an explanation about your body. If scars bring up distress or urges, that is something you can talk about in therapy too.
Most importantly, a history of self-injury does not mean you are destined to keep doing it. Coping patterns can change as support, treatment and emotional skills improve.
Living with and recovering from self-injury
Self-injury can create a private life inside your public one. You go to class, joke with friends and do normal things while also worrying that someone will notice, wondering when the next urge will hit or feeling ashamed afterward. Recovery gets easier when that private struggle is not being carried alone.
Tell a safe adult
If you are a teen who is self-injuring, telling an adult can feel terrifying. Choose someone who has shown they can take serious things seriously. You can start with a simple sentence: “I’ve been hurting myself and I need help.” You do not have to explain everything perfectly.
If a friend tells you they self-harm
Stay calm, listen and encourage them to involve a trusted adult. Do not promise to keep self-injury secret. That can feel like betrayal, but another teenager should not be responsible for managing someone else’s medical and suicide risk alone.
Avoid shaming, demanding to see injuries or turning the conversation into an interrogation. Your job is not to become their therapist. Your job is to care, help connect them with adults and get emergency help if they are not safe.
Build a plan for the urge, not just the aftermath
Work with a professional to recognize the emotional buildup before the urge peaks. The plan may include leaving a triggering situation, contacting someone, grounding, movement, writing, music or other coping skills that fit you. The important part is practicing alternatives before you are at your limit.
When to get urgent help
If you are thinking about suicide, are unsure you can stay safe, have seriously injured yourself or are in immediate danger, get help now. Tell a trusted adult. In the United States, call or text 988 to reach the Suicide & Crisis Lifeline. In a life-threatening emergency, call 911 or go to the nearest emergency department.
A note from Project Semicolon
Self-injury can become a way of saying something your words have not been able to say yet: this hurts, this is too much, I need relief, I need someone to understand.
You deserve a response to that pain that does not require you to hurt your body to make it real. Telling someone may feel like losing control at first. It can also be the first step toward having more choices than the urge gives you.
