What am I going to do?

If you're this desperate and afraid of what's going to happen to you, being 14 you need to sit your parents down, and tell them what's going on with you. Turn off the tv, turn off the phones, and make them listen to you. If they still won't listen to you, try another relative, and make it clear that you're as stressed out as you are. You should also try talking to a teacher or school counselor about it. If your problems are as severe as you say, the school can get your parents attention, and get the ball rolling on getting you the kind of help you really need. Good luck, sweetie.
