just wanted to validate a lot of what ur saying
yes, i do think in america there is more awareness of narcissism, and bingo, a lot of hopeless mental health practioners (or maybe well meaning, but still hopeless, ones) fall prey to this age-old, dated idea that like, families should be together, no matter what, that parents love their children, always, and that repairing damage often means "forgiving" an abusive family member in the name of family peace. No, no and no.
I also saw a really old psychiatrist who was really bad about this stuff and tried to have me do family therapy with my abusive parent. It was awful. Some ppl are so old-school abotu these ideas.
I didn't find the hospital super sensitive about traumas or abuse, and I've also been a few times. It's definitely not fool-proof advice, but I'd recommend avoiding the 75 year old white male model of psychiatrist or doctor, and be open to seeing female, younger, or modern thinking, therapists, they may get it. They may have seen it all before. They may even get it very quickly, and immeidately see what's up and what your mother is doing.
You've gone through a lot, i hope u are able to do the yoga training and to find some space from ur family, and feel a bit better after all that you have been through. sending care and support.
