My mom is so frustrating?

Ever since I was little my mom would swear at my brother, my dad, and I. She picks fights at the smallest things and she doesn't seem to realize that she's causing everyone's misery. My mom is so degrading and belittling, I feel like that's the reason why I'm introverted. Ever since day one she's never let me voice out my own opinion, and so this is reflected on the way I act in public and around people. I've been raised in a way that has taught me that my questions are stupid therefore I don't ask questions anymore. My brother moved out when he went to university, he tells my mom it's because he doesn't like commuting to a different city, but he told me it's because by living by himself in the city he's able to meet people and discover that his opinion matters. Even my mom has noticed how he became an extrovert when he went to university, but she doesn't realize that it's because he isn't living in the same roof as her where she belittles everyone 24/7. She's always swearing and blaming people for accidents, or things that normal people wouldn't make a big deal about in the first place. She's always on edge because she doesn't trust the world, and she has told me those exact words. I have tried to have multiple conversations with her trying to sort out this issue, but there are just some people who you can't get through to. I'm 16 now, what should I do?
