Seriously get a therapist. You've obviously got some problems and if you feel that you can't even talk to your parents, you need to fix that shit right away. Your best short-term option is to simply go to your parents and be 100% serious, telling them everything you told us. If you're comfortable telling strangers on the Internet, you should be able to talk to your mother and father. Don't let them shrug it off; make them listen. I'm confident they will.
