I can totally identify with what you wrote. In fact I might have written something similar about my relationship with my mum. Both of my parents were quick to anger. They would commonly say very harsh things. Although there was never any physical violence. I suspect that you mum, like mine, is unhappy in her own life and somehow seeks to address that by "correcting" you. But you are not responsible for any mistakes and wrong choices that you mother made. I don't think you're doing anything wrong. It's very hard to deal with parents who are this controlling!
