Hi:

Sorry to hear of your problems.
My mother and I never saw eye to eye either, she is exceedingly overbearing as yours is, and quite verbally abusive. However, I did cut contact with her considerably, and live quite a ways from her, this has helped me enormously. She falls somewhere in the Narcissistic range, sadly.

Is there any way you can get a place of your own, or some space away from her?

May I suggest a good book I read a few years back:
"My Mother My Self" by Nancy Friday (The Daughter's Search For Identity). It talks about changing childhood patterns we learn from our parents, and our relationships with women in general etc....very enlightening read, I hope it helps you.

Have you thought about going to see a therapist to talk about it, might be a good idea. Perhaps he/she can offer you some insight and perspective

Most of all try to get yourself some breathing room, it does not sound pleasant You deserve respect always remember that.

Blessings,

Just some ideas, hope they help.
