Mood Disorder: Precursor of Suicide?

Suicide Edwin Shneidman  suicide is an intentioned death – a self-inflicted death in which one makes an intentional, direct and conscious effort to end one’s life.

Shneidman has distinguished four kinds of people who intentionally end their lives :  Death seekers have a clear intention of ending their lives at the time they attempt suicide.  Death initiators also clearly intend to end their lives, they act on a conviction that the process of death is already under way and that they are simply hastening the process.  Death ignorers they believe that they are trading their present life for a better or happier existence  Death darers are ambivalent in their attempt, and they show this ambivalence in the act itself.
