Talking about the cry for help and accidental suicides.... A friend of mine from high school did this at the age of 16.
I'll try to keep a long story short.
His mother died when he was born, he grew up being passed between his father and grandparents. In his own words, his father blamed him for his mothers death because if she didn't give birth to him she wouldn't have died, he always felt a coldness and resentment from his father. At the age of 14 his grandparents were killed in a car accident so he was left living with his father, not long after this his father started ramping up the verbal abuse which ended up turning physical.
One day at school he said that when he got home he was going to give his father the shock of his life, he was going to pretend to hang himself, he would be standing on a chair with a rope around his neck as his father walked through the door. We tried to talk him out of it and he said he wouldn't do it, well he did it, and he made the mistake of using the computer chair that had castor wheels... I've always wondered if it was an accident or if he actually intended to go through with it, like his telling us about it was some kind of warning to prepare us for what was about to happen.
Every single time I hear the word "suicide" I think of this poor kid, he had a really shitty life.
Stories like his make me understand why someone would take their own life, even though it's something I could never see myself doing.
I personally don't have a problem with it, it's a very big deal, and if someone is in such immense pain that they wish to take that path who am I to stop them if they will finally be at peace, same goes for terminally ill people. I don't want to glorify suicide, just saying that I get it.
