Hi,
You could very well have an underlying bipolar disorder. Esp. with an onset in your teen years. Check out my bio. I hope you can trust in us. I am a psychiatric nurse and have bipolar. I am going to direct you to some informative sites, so you can sort things out. Find a good psychiatrist that specializes in mood disorders. You have alot going for you, so you need to nip it in the butt, so you can have a long productive normal life, and look forward to college. I have an 18 year old who will be going to college next fall.
