I hate my mom?! what to do?

I seriously hate her! She's mean, stupid, and traets my brothers better. She yells at me for no reason like asking where the bread is or something else stupid. My brothers got new shoes and I got nothing. My brother yelled at me for being on the wii and she did nothing. My other brother got mad when I sat on the couch and started yelling. And my mom once again said nothing but when I said why did u look ay my like that to my brothers she made me apologize. She always say that I play the victum and I have a bad attitude. But r u serious they do everything and get away with it. And I can't say anything because every time I try she just cuts me off and saids I don't wanna hear it. Last weekend thy we're going out to a resterant and she said I couldent go cuz I hit my brothr but seriously they beat me up. When she left I started screaming and I eventully cut my self for times. I was so mad I put a dent in the refrigerator. Idk what to do hlp I need answers plzzzz
