Is it normal i hate my house?

All my life my brother (who's almost 2 years younger) has stressed me out. Ever since we were kids, all I can remember from our relationship were constant fights. We never really made much of a connection when we were kids because he always pushed me away. I never had confidence as a child, and he always had a big mouth and would say words that have stuck with me into adulthood. Whenever we're in the same room, I always felt pressed and there was tension in my head. I hated being near him, and that just made him want to be near me more in order to pester me for fun.
I developed depression and anxiety after childhood, the numerous insults and attempts to belittle me stuck as I grew up. Now I'm always uncomfortable around my house. I'm always prepared for the next attack he's going to give. Over the years it's died down, but he's still a real asshole. He's incredibly inconsiderate of others feelings (especially me and my mothers) and when he does't get what he wants, he'll make sure you know he's angry. Everyday is the same, and I don't know how much longer I can stand his selfish and harsh personality. For no reason, he'll make fun of how I look, dress, act, say something..etc. Nothing is off limits to his remarks. I love being reminded everyday how much he hates me as a sister :). I used to be wicked emotionally unstable and react incredibly poorly for a period of time because it just became to much for me. And I always felt alone because my mom would just let the abuse happen. Physical and emotional, and I honestly have some resentment for both of them sometimes.
I just feel so stuck and I don't know if it's normal behavior for a brother to act in a way that he does. I see other families, and they all get along nicely and seem so happy. I hate to compare, but when I see happy families that surround me, I feel so alone in what I'm experiencing. They can go out to eat without hating each other once we arrive back home. There's always a new problem. Im sick of it.
