Mom is always furious and screaming is there anything I can do?

I left because the tension was hurting my body and I am way too old to put up with this. Also she kept yelling at me in public for things I have no control over. For instance, me spraining my ankle and my car dying.

When I come to help, she treats me like crap and makes feel bad for not being a buffer for her non stop fights with my father. She blames me for my nieces and nephews not wanting to visit, because she is mean to them. She is also mad , I am friends with this older lady, and we do mother daughter stuff together. Because my mom doesn’t go anywhere and thinks my interest are stupid.

Everyone at work hates her too and she rants about that too. I thinks it’s the starvation diet she is on , she can’t eat anything but spinach and special shakes to lower her cholesterol. She was always bad, but the new cholesterol pills make her very aggressive. She doesn’t sleep. I think she is starving, but she won’t eat normal food. Because her quack diet guru says all normal food is bad.
