Just to make things clear, im 14 now

well, I didnt know it at first, but 2 or so years ago (when I was worst), I was really shy. The slightest thing would upset me, to where I would get extremly (and oddly) angry (like someone would blame something on me). I was really close to my family, but I hardly ever spoke in public. Also I was ahead in my math while most people were behind me. I never wanted to go anywhere. I think im good at memorizing numbers too. I also have horrible handwriting


now, though, im a lot better socially, but I still exibit several of the symptoms.


And something else I dont understand. Whenever I get mad, its so extreme that I do weird things, like hit myself, moan loudly, and other things...I know that sounds weird, but I need to know the cause...Thanks for any help!
