I hate my mom so much?

[Lovely]

I hate my mom so much. She always gets angry and she always proritizes my younger sister over me. She always yells at me about little things and i always be equated with my sister that younger 4years than me. But when my sister makes a mistakes my mom always says "She's still little and its your fault not her fault" btw i'm 14 and my sister is 10 but she has twitter, tumblr and her phone even greater than my phone when i was 12. Mom always defends her but when i say "you always defend her" and mom comes to me, slaps me and yells at me. But i love my dad, he's so fine and i dont know why but my mom always thinks that my dad defends me always which he doesnt. and mom always says "your father always defends you, dont cry, if ur dad sees his gold princess cries, he will blame me" and mom likes to mocks me, like "you jerk, bitch, ugly" and im very sad about that. I dont have friends for 5yrs cuz i'm homeschooled and mom dazn let me to have twitter/facebook or anything. what should i do?
