Sad it happens, mystery as to why it happens. Often the family and circle of friends of a suicide "victim" can never reach an adaquate answer, usually feeling guilt and even at fault for the tragedy, these people truly are the victims. Causes,? as many as can be thought of. Obviously mental instability, and not meaning mental intelligence either. May sound harsh but probably internally speaking "selfish" minded, they comprehend that no one is as important as their situation. They fail to realize or comprehend what their decisive final action will do to those who love them, and beleive me often times perimiter friends love them as much as family, or possibly more. They at that moment are weak in many ways and those weaknesses attempt to place blame (rationalizations) in all directions. It's something that cannot be sugarcoated with excuses, that is only a way people cope with what has happened. It brings a lifelong feeling of sadness, emotional pain, nagging questions and often unwarranted quilt to others.
