Is it normal dad always mad at his teenage daughter?

I dunno know what else to do.I try and get as many hours as I can from work.I can't wait for school to start. I do have a messy room . I put gas in my car. I do my own laundry most of the time.I don't stay up past curfew. I try to stay away from my dad as much as possible.Other people feel bad for me because he is always yelling at me It makes me really nervous which makes him yell more. It is so embarrassing.As soon as I walk in from work or wherever he starts screaming like a drill sargent stomping around and slamming doors , yelling at what I did wrong today.
We don't eat as a family anymore.because my dad would sit there and pick on me the whole meal until I barfed and my mom left the table in a huff. Sometimes i eat with my dog on the patio and alot of times my mom comes and eats with me.My mom tells him to stop it or she will leave and then he blames me for making them fight and breaking them apart. She also tells me to ignore him because he is an asshole.I can't even watch tv without him coming in and calling me stupid or lazy. If I don't say anything I get in trouble for not talking to him. If I stand up for myself after he has been yelling in my face for 45 minutes , I get in trouble. He just started doing this a couple years ago.I have asked why he does this and he says because I am a loser just like him and it is to help me not be a loser. Yeah it makes a lot of sense.
