That sucks. Maybe just shut her down? Tell her it’s not appropriate to discuss your mental health in public (or company if others). Heck, maybe just tell her you don’t want to discuss your mental health with her any more. If you feel like it, throw in that you love her. Or not.

I know, all of that is far more easily said than done. I could rant about my family members too - so much of the same kind of thing!!! I’m just now learning that I can shut them down. I can tell them that whatever their opinions are about my mental health and how I live my life, I’m not interested in hearing them. And by the way... and change the subject. For me, it’s working better than I expected.
