I dunno about that. last October... (damn almost a year ago on the nose) I nearly lost my life (as you know). Now... I wasn't trying to kill myself at that moment. But I had made some morbid comment about not living much longer, just the night before it happened.
Had I died... it would have been MY fault, for driving drunk. So... essentially in my case it was almost the same thing as suicide.
In one of my brief stays in the nut house (yay for psych-issues!), my roomie had lost her husband to suicide. She only wished that there was something she could have done to prevent it.
The truth is, only SELFISH PEOPLE would call someone who took their life "selfish". If its someone you truely cared for who is gone... you'd be confused, hurt, maybe breifly angry.... But, mostly you would just be wondering what you could have done to make that persons life a bit easier. If its not someone you cared for, you have no place analyzing their circumstances. Period.
