I agree with what other people have said in that you should consider talking to someone you trust about this, like a teacher or a school counselor. It will probably help because you won't have to keep this all to yourself anymore. It is possible that your counselor can bring your parents in and act as a mediator so you can say what you feel you need to say to your parents.

Once you're eighteen, your parents cannot keep you at home anymore. I highly suggest coming up with a plan so you have another place to go when you're legally an adult. I like the idea of speaking to relatives who won't tell your parents, or maybe speaking to your friend's parents to see if they can take you in for a while or help you find a place to live.
