I need advice on handling a difficult mother/daughter relationship?

I’m currently living with my mother and tensions are running high. We argue a lot, which makes the atmosphere very tense. She’s very bitter and has a lot of resentment towards me. When we argue, she says absolutely horrible things to me – she belittles me in front of others, etc.
The worst thing to deal with is the way she ‘tries’ to control me. She tries to involve herself in my every decision and if I don’t go her route, she’ll constantly remind me that I’ve made a bad choice(in her opinion).
Sometimes I feel like she’s trying to live through me. It’s really getting difficult to stay here. The problem is, I simply cannot afford to move at the moment. It doesn’t seem to be an option for me. I’m barely surviving financially living with her.
Just to add, I pay her rent every week & buy my own groceries, etc
Does anyone have any suggestions about how to improve the situation until I get on my feet again and find a place to live?
I’m 24 by the way.
