I have aspergers syndrome. what should i do?

hi, im 12 years of age in july, i've recently been diagnosed with a mild case of aspergers syndrome and i don't know what to do about it. i feel like my life is falling to pieces, and everything is going wrong. sometimes, i cut myself, and this week at some point, i have to talk to the doctors about it. i have a huge phobia of hospitals, doctors, needles, most medical things, but one of my obsessions has been health lately. i thought at one point i was a hypochondriac. i feel like im getting depressed, i hate everything about myself, and i panic a lot, i get scared easily, im really insecure, i have tons of phobias. um, i cant look people in the eyes, i don't have a lot of friends, im a computer geek. uh... im not supposed to be on my laptop anymore, 'cause my mum thinks im getting addicted. if i don't have something sugary/chocolatey every day, i get really stressed out. i just found out my mum's boyfriend got raped as a child. my mum doesn't know. her boyfriend doesn't know that her ex-boyfriend stalked us, and we had to call the police a lot. i have a short temper, and i get stressed extremely easily, to the point where i feel like crying. i hate homework, i never want to do anything. im anorexic, and some days, i eat nothing, some days i binge eat. i talk to people online, and i've kinda fallen in love with my online bestfriend who's 19, and lives about 40 miles away, though i've never met him. i feel like i just don't know what to do anymore, and i'd really like some advice. thank you. <3
