As someone else who has done this I can only explain my own reasons; I carefully planned it out waited until my flatmate had left me alone went to the shop bought as many pills as I could then took them all. I then ended up phoning a friend soon after, what made me do this? Well, it was like there were two people in my head, one wanted to die and nothing was going to stop her, she'd had enough of the pain of this world and was a sink of despair, self-loathing and hatred. Then there was another person in there a frightened little girl who didn't understand why her world had been turned upside down and didn't understand why she was hurting and what she'd done. It was the frightened little girl who phoned my friend, who then phoned an ambulance. Unfortunately there are still these two sides to me and sometimes it looks like the dark side of me is going to win.
