----Be assessed by a professional if you haven't already. Talk to your parents and school counselor. Whether you have a diagnosis and what it is, is very important in trying to get an answer to this question. What makes you angry? Just the immediate situation or do you think that underlying things in your life are making you angry? If I was your parent I would have you do these things and have you do vigorous exercise as an outlet, and possibly pursue other hobbies.. As to why you don't have any control: If you don't have a diagnosable condition, and sometimes it takes a while to get a diagnosis, remember that the teen years include huge transitions and your brain is actually still growing. And your hormones are raging. You are not ignoring the problem, so you are that much closer to some solutions! If you feel that the problem is that you cant express yourself verbally, consider an assertiveness class. Good luck!
