There's been a lot of good advice in this thread, so mine probably won't make any difference.
But self harm is the definition of pointless. If you do that, you'll have all your mental problems, plus you'll have physical pain on top of that. You don't want to be in that predicament. If you must release anger, then break something, just do no harm to yourself in any way. This is important.
Problems can be solved with words. You must talk with the people in question, or think a lot to yourself. There's always a way out.
