I am so fed up of my mother.

I want to move to my dads but cant. She comments about my brother and i's body sometimes and is just honestly so hard to live with sometimes. She also makes me feel embarrassed about my period. She comments about my dad. She also is just so weird sometimes. She is homophobic and racist and I'm scared to ever come out to her and am afraid she'll pass it onto my younger impressionable brother. She always has to be the victim. I end up staying up at night alone so i can just be quiet without her having to talk to me all the time. And tries to make me feel bad about my half sister and stepmum. When in reality they are so nice and i love them.
