How do I get rid of this kind of anger?

Make them even angrier without jeopardising your safety. Run away. Move out and stay with friends or relatives. Trash the house. Go on strike -- never do anything they want you to do. Lock yourself in your room. Phone up abuse helplines and ask for advice and help -- you ARE being abused. Get your doctor involved -- say your parents are mad and that you want them committed. Do whatever you want to do whenever you want to do. Never ask for permission. In fact, always do the opposite of what is wanted. Do all of this until you have their undivided attention, and then spell out your demands. You are the sane one in this family, so you should be the one calling the shots.
