Your situation is different from mine because I live far away from mine. Also, Thank God, I do not work for her or interact closely with her.Your mother does not sound as bad as mine,either.
N's are on a continuum, I think.My H has N qualities. However, his father was a Super N-worse than my mother.
My mother has a psychotic world view . I am damned if I do and damned if I don't. If I try to share it with her-which I chose to since age 14- then I am crazy as a loon,which I was. If I reject it, she wants to kill me.
I don't think that your mother is this bad. Also, with mine, she uses the therapy to justify her world view.
I want everything to be the best for you. You have been through hell and deserve a life of dignity
Love Ami
