It could be tragic, but you can't blame the MC for a shitty life. I know schools have programs to help students (although most students don't seek help because they don't want more torments at home, so you as a teacher or classmate, pretty much can't do anything without the risk of making it worse) and if you torment somebody else, just because you had it rough... Yeah, the only thing you are doing is making it worse for you and possibly breaking somebody else.
