Do I need a counselor?

My mom and I never clicked so much during my 17 years of being here. I'm a typical girl who never did anything under the influence. Never had a serious boyfriend, never had her first kiss yet. Never been to the principal's office...I consider myself pretty decent amongst other peers in my school. Bit for some reason my mom always had something to be mad at me for..When I was naughty at the age of 4 my mouth was 'cleaned' out by liquid soap, she would drag me by the hair around the house and spank me. I remember she got so mad at me when I was 9 she slammed my door 3 times each time she screamed "go to he**!" in recollection she has told me the following more than 3 times.. You are anorexic...Are you on a diet or something?..you're a skeleton..you have no friends..you will never have friends/boyfriend..you will never be successful..you will never graduate high school..you should just drop out..you will never be pretty...you are the devil..you are just like my crazy brother steve..your ugly inside and out..You won't graduate from college...now for the physical...shoved against wall bed etc..bloody nose..minor bruising..slapped in face etc..dumped me off from the car in the middle of no where..chased around the house and public while screaming...etc etc..she never is happy with me..and having OCD,anxiety,ADHD,depression and insomnia doesn't help. If anything she created my depression, my slf esteem and lack of friends...My other aunts have major problems and kids of their own and my nana and papa are too rich to ever consider to stay with them for awhile..my dad lost his career in 2005 and we barely make enouh to pay the bills...my dad has major anger problems too but my mom is worse. I stopped them from splitting last year after I collapsed on the driveway to make my mom stop from driving away..but she threatens sometimes she will Leave with my brother and drive off leaving me alone. I don't know what to do. I just lost my bestfriend because I told her that she should take care o herself and not do dru*gs but she got really mad. I can't talk to anyOne about this..I feel so alone and depressed. My grades are starting to slip a bit from all the stress. I feel so worthless and now I'm beginning to believe allthe insults my mom told me over the years. I'm a total loser.
