vent about dad

I moved in with my dad 2 months ago, after living the last 16 years with my mom. He never was a fatherly figure in my life, and I overall have never liked him. Whenever he gets upset he just finds more and more reasons to be, and will shove all his grudges against me and everything wrong I've done down my throat. I'm very afraid of him. The only times he has physically harmed me was when I was very little, but I still  know the violence he has done and the capabilities he has. The only reason I moved here was because my mom grew very mentally ill and we lost our home, as she grew unable to even take care of herself. She is now in a mental institution and hopefully she can heal. I cannot wait to get out of  here though. I feel like I'm living with a stranger, and am tired of the constant anxiety I feel about his anger. Oh also, he's a severe alcoholic and either gets drunk every night or crossed. I know I should feel thankful for him giving me a place to stay, but I want to get out of here so badly.
