Suicidal behaviors can accompany many emotional disturbances, including depression, bipolar disorder, and schizophrenia. More than 90% of all suicides are related to a mood disorder or other psychiatric illness.
Suicidal behaviors often occur in response to a situation that the person views as overwhelming, such as social isolation, death of a loved one, emotional trauma, serious physical illness, aging, unemployment or financial problems, guilty feelings, or dependence on alcohol or other drug.
In the U.S., suicide accounts for about 1% of all deaths each year. The elderly have the highest rate of suicide, but there has been a steady increase among adolescents. Suicide is now the third leading cause of death for 15- to 19-year-olds, after accidents and homicide.
Suicide attempts that do not result in death far outnumber completed suicides. Many unsuccessful suicide attempts are carried out in a manner that makes rescue possible. These attempts often represent a desperate cry for help
The method of suicide can be relatively nonviolent (such as poisoning or overdose) or violent (such as shooting oneself). Males are more likely to choose violent methods, which probably accounts for the fact that suicide attempts by males are more likely to be completed. Many suicides involve a firearm. This is especially true in elderly men, in which 80% of suicides are performed with a gun.
Relatives of people who seriously attempt or complete suicide often blame themselves or become extremely angry, seeing the attempt or act as selfish. However, when people are suicidal, they often mistakenly believe that they are doing their friends and relatives a favor by taking themselves out of the world. These irrational beliefs often drive their behavior
