I disagree with the ones in bold, especially with the rape part. Rape can be incredibly difficult to prove sometimes, and seriously, it can and most likely will fuck a person up for life. There's this weird social stigma going on with rape, making it hard for people (especially men) that have been raped to come out and say it, as if it's a mark of shame. Of course it mostly depends on where you live, but still, you're oversimplifying it way too much. Same with being abused at home. Kids who are abused get so mentally fucked up that they'd be too scared to do anything about it. You can't brush it off as if it's a matter of calling up the police >_>
As for being bullied at school, most of the times kids that get bullied don't tell their parents/administrators, because they either won't care or because the kid thinks it will make it worse. I do think being bullied in school is nothing to commit suicide over, but it depends on how bad you're being bullied, I suppose.
I never meant to imply otherwise. Nothing wrong with being selfish; it's their choice and I don't have any illusions about trying to stop them if they truly made up their mind. Some, usually teenagers, are too hasty with the decision though.
