I also armchair diagnosed by ex-best friend with BPD...I mean, based on a decade of behavior, a decade of her sisters behavior, and a decade of her mom’s behavior...but yeah sounds extremely similar to your situation.

I mean, I hate to get defensive on behalf of the OP, but it’s rarely that simple...

I had a similar discussion (using that term loosely) though with a stranger on a former coworkers page (spoiler: he deleted the post). It was a post about the women’s march, and when I pointed out the backwards logic in the post was called “whiny” by a woman who did not address any of my points, and then deleted her…

Been there! At first, I was shocked how unreasonable everyone else in her life was.
