I'm a 20 years old girl , my father is ruling my life . He always does things what he likes .?

He's least bothered about how I feel about his decisions. I always wanted to die,as he never gives me what I want. Since my childhood he always beats me for small things and uses foul language to me. Now he's changing my college without my interest ,when I said I don't want to change he scolded me , now he's telling me that if I get less marks in the present exams the admission gets Cancelled and you can't join anywhere and I really screwed up my exams as i'm unable to study what he's given me. He cons fused me a lot ,I don't know what to do and how to handle situation and I feel like killing myself or running away from my home as I've been facing this as a baby .I don't know why does he hate me so much .he says he hate girls ,well in that case why does he love my. step sister and let's her do everything she wants .i don't know what to do whether to leave my home or not as I've no support either financially or anything and what should I do ?I know I'm complaining a lot for a small problem ,what to do it's the biggest pain my heart .and I go complain my mother but she's says he doesn't listen to her even my mom scarificed a lot for us and she didnt say anything even though even though my father married again my moms own sister . Please do advice me something .how to handle my life ? What should I do ? Should I just commit suicide .I'm literally unable to bear this pain in my heart:
