Your mom sounds mentally ill. She is the problem, not you. Do you think that there is any way that you can withdraw yourself from her drama? Refuse to be drawn into it? Just sit back, listen, watch, walk away but don't get pulled in? You know, you don't have to convince her of anything. You don't have to convince anyone of anything. Explaining/defending yourself to someone who will just twist it is a bottomless pit. It will suck the life out of you.
