Kellerman et al, Suicide in the home in relation to gun ownership. 1 Suicide data was obtained from vital statistics on the underlying causes of death prepared annually by the National Center for Health Statistics at the Centers for Disease Control and Prevention. People who talk about killing themselves rarely commit suicide. The tendency toward suicide is inherited and passed from generation to generation. The suicidal person wants to die and feels that there is no turning back.
All suicidal people are deeply depressed.
Although depression is often closely associated with suicidal feelings, not all people who kill themselves are obviously depressed. Also, people who are extremely depressed usually do not have the energy to kill themselves. There is no correlation between alcoholism and suicide. Alcoholics are prodded to suicidal behavior and even people who don't normally drink will often ingest alcohol shortly before killing themselves. Suicidal people are mentally ill.
