Man this reminds me of this girl I knew who would cut on the bus and at school. She was open about her fucked up life, her dad raped her a lot when she was younger etc. Except it was the opposite, everyone made fun of her, tried making friends with her but she thought I just wanted sex and eventually disappeared but she often would talk about killing herself to send people a message. To this day I still wonder what ever happened and kinda play that scene in The Butterfly Effect near the end.
People suck.
But there was a successful one right after school, she was 14. Her brother talked her into committing suicide together (he was my age, like 17). She went first, watched her blow her brains out and backed out.
There were two more so I'm getting the vibe I went to a fucked up school.
