Yes, she regrets life. Does this mean you must also?

Why do you think she would be able to act normally to her carers in a nursing home? I think she would yell at them too.

Somehow the tables must be turned. I wish i had advice for you. I left my mother. She did not even act as loudly as yours, but i too felt my body could not take it anymore. It was her or me. If i had stayed, i would have died from stress. But it was easier for me to leave, as she did not take care of me when i was small, my father did.
