Suicide is the act of taking one's own life on purpose. Suicidal behavior is any action that could cause a person to die, such as taking a drug overdose or crashing a car on purpose.
Suicide and suicidal behaviors usually occur in people with one or more of the following:
People who try to commit suicide are often trying to get away from a situation that seems impossible to deal with. Many who make a suicide attempt are seeking relief from:
Suicidal behaviors may occur when there is a situation or event that the person finds overwhelming, such as:
Risk factors for suicide in teenagers include:
Most suicide attempts do not result in death. Many of these attempts are done in a way that makes rescue possible. These attempts are often a cry for help.
Some people attempt suicide in a way that is less likely to be fatal, such as poisoning or overdose. Men are more likely to choose violent methods, such as shooting themselves. As a result, suicide attempts by men are more likely to result in death.
Relatives of people who attempt or commit suicide often blame themselves or become very angry. They may see the suicide attempt as selfish. However, people who try to commit suicide often mistakenly believe that they are doing their friends and relatives a favor by taking themselves out of the world.
Often, but not always, a person may show certain signs and behaviors before a suicide attempt, such as:
People who are at risk of suicidal behavior may not seek treatment for many reasons, including:
A person may need emergency treatment after a suicide attempt. They may need first aid, CPR, or more intensive treatments.
People who try to commit suicide may need to stay in a hospital for treatment and to reduce the risk of future attempts. Therapy is one of the most important parts of treatment.
Any mental health disorder that may have led to the suicide attempt should be evaluated and treated. This includes:
Always take suicide attempts and threats seriously. If you or someone you know is thinking about suicide, there are numbers that you can call from anywhere in the United States, 24 hours a day, 7 days a week: 1-800-SUICIDE or 1-800-999-9999.
Call the local emergency number (such as 911) right away if someone you know has attempted suicide. Do not leave the person alone, even after you have called for help.
About one-third of people who try to commit suicide will try again within 1 year. About 10% of people who threaten or try to commit suicide will eventually kill themselves.
Call a health care provider right away if you or someone you know is having thoughts of suicide. The person needs mental health care right away. Do not dismiss the person as just trying to get attention.
Avoiding alcohol and drugs (other than prescribed medicines) can reduce the risk of suicide.
In homes with children or teenagers:
Many people who try to commit suicide talk about it before making the attempt. Sometimes, just talking to someone who cares and who does not judge them is enough to reduce the risk of suicide.
However, if you are a friend, family member, or just know someone who you think may attempt suicide, never try to manage the problem on your own. Seek help. Suicide prevention centers have telephone "hotline" services.
Never ignore a suicide threat or attempted suicide.
