My friend self-harms and most likely has depression but I have no idea what to do to help her. I don't know how serious it is because I've only recently found out. She says no one can help her and sometimes she wishes she was dead. I want to tell a professional but she's asked me not to tell anyone and I don't want to break her trust. Another thing is she dismisses it whenever I try to bring it up saying I can't help! I don't know what to do because she's only 13.
