Where to find support? (long)?

Well.. My mom has always told me I never amounted to sh**.. & it's because of the way I look. Ever since I was young she has never said something positive about me. Always called me ugly and fat and never stood by my side or has been proud of me. I'm 23 years old.. A CNA & HS graduate. Currently pre-med. She told me I'd never graduate HS & she never attended my graduation when I graduated. She hates my guts. I don't understand why?? Shes always comparing me to other females saying they're better than me she even claims she's better looking than me because she's smaller. When she calls me names I now laugh cause I'm used to it.. But it hurts EVERY DARN day of my life is the same bullcrap. She never wants to go out with me cause she's ashamed of how big I am. I'm not even morbidly obese how she makes it seem. I'm just heavy set & not a size 0 how she wants me to be. Recently my cousin (she's 20) got pregnant.. & a family's friend daughter I gre up with.. She's 22.. Also got pregnant.. & my mom said I'll never have kids and will always be alone cause nobody wants me... I HATE HOW SHE TREATS ME!!!!! why does she hurt me? Isnt she my mother?? I lost my dad at 7 when he passed.. & she's the only parent I have left. Why am I so unlucky?? I don't bring her any problems. I don't drink, don't smoke.. I'm not a bad kid.. I love my studies.. Im abstinent.. Im still a virgin & I've never brought any men home. I'm tired.. Someone give me advice. I have no other mother figures and life just feels like I'll be exactly what she says I'll be.. A nobody... I'm trying my hardest to move out but the economy is real bad! I'm trying to do the impossible to have my own space...
