Most suicidal individuals give warning signs or signals of their intentions. The best way to prevent suicide is to recognize these warning signs and know how to respond if you spot them. If you believe that a friend or family member is suicidal, you can play a role in suicide prevention by pointing out the alternatives, showing that you care, and getting a doctor or psychologist involved.
Major warning signs for suicide include talking about killing or harming oneself, talking or writing a lot about death or dying, and seeking out things that could be used in a suicide attempt, such as weapons and drugs. These signals are even more dangerous if the person has a mood disorder such as depression or bipolar disorder, suffers from alcohol dependence, has previously attempted suicide, or has a family history of suicide.
