What are the warning signs of suicide?
What if there are no warning signs?


From WebMD:

Most people who seriously consider or attempt suicide have one or more of the following risks:

• A personal or family history of suicide attempts
• A family history of suicide attempts or completed suicide
• A personal or family history of severe anxiety, depression, or other mental health problem, such as bipolar disorder (manic-depressive illness) or schizophrenia
• An alcohol or drug problem (substance abuse problem), such as alcoholism

The warning signs of suicide change with age.

• Warning signs of suicide in children and teens may include preoccupation with death or suicide or a recent breakup of a relationship.
• Warning signs of suicide in adults may include alcohol or substance abuse, recent job loss, or divorce.
• Warning signs of suicide in older adults may include the recent death of a partner or diagnosis of a life-limiting illness.

Anytime someone talks about suicide or about wanting to die or disappear, even in a joking manner, the conversation must be taken seriously. A suicide attempt-even if the attempt did not harm the person-also must be taken seriously. Don't be afraid to talk to someone you think may be considering suicide. There is no evidence that talking about suicide leads to suicidal thinking or suicide. Once you know the person's thoughts on the subject, you may be able to help prevent a suicide.

WebMD also goes more in depth of the warning signs of suicide in children, teens, adults, and older adults.
