I hate my brother..

I abhjor my mother too..I don't know if that makes me a bad person..may be it does..My mom makes my life hell. She loves my brother to distraction..and will give him whatever he asks for..while she's always always saying mean things to me..from the time I was a kid..she's always been mean to me even tho I have never done anything which makes me deserve it. I feel so screwed up inside. She hits me, and abuses me and loves to humiliate me. While at the same time she spoils him. This is affecting my stduies and my life. For instance, before each exam she makes it a point to say something mean which always spolis my mood. While studying also he always gets the good room, while mine is right next to the sitting room where they watch TV loudly which is very idstracting. My brother just made it into one of the top schools..while I am stuck with a job which pays half of what my school frineds earn. I am 25 and still single with no prospects of getting married. My parents insist on me living at home, and then as rent demand most of what I earn. I feel like such a loser. I feel awful. This was not what I had dreamt of when I studied so hard, struggled so much...I am very very sad and I can't take it anymore..especially my bitch mother and her meanness. Why did she ruin my life like this?
