Hi,
It's been a while since you posted, but I wanted to make sure you had a response. It's very important to talk with a trusted/safe adult about your feelings right now- it very well could be puberty (those hormones can make for a wild ride!)- or there could be something more serious. I know if my son was feeling this way, I would want him to talk to me- hopefully, your parents would be safe to go to, to talk things through as well. If not, you might try another safe adult- also don't hesitate to talk to your doctor about your thoughts and feelings.
I hope you are able to reach out to someone soon- let us know how you are doing!
I also get very angered easily during the hyper and happy outbursts
