I think I have a big problem. Please help me, I want it go away?

Before this gets any more serious and out of control, you need to get some help. There is treatment for this. Get some therapy. You won't get in trouble because you haven't done anything. With therapy, and possibly medication, you can hopefully overcome this. Therapy will help you get to the root of it, and help deal with it, control it, and eventually stop it.
