Causes

By Mayo Clinic staff

Suicidal thoughts have numerous causes. Most often, suicidal thoughts are the result of feeling like you can't cope when you're faced with what seems to be an overwhelming life situation. These situations could include financial problems, the death of a loved one, a relationship breakup or a debilitating illness. If you don't have hope for the future, you may mistakenly think suicide is a solution. You may experience a sort of tunnel vision, where in the middle of a crisis you believe suicide is the only way out.

There may also be a genetic link to suicide. People who complete suicide or who have suicidal thoughts or behavior are more likely to have a family history of suicide. While more research is needed to fully understand a possible genetic component, it's thought that there may be a genetic link to impulsive behavior that could lead to suicide.
