I myself find it so infuriating when people claim this and that is a trait of BPD when it is quite clear what the traits are by reading the DSM. People can't just add on these different things not sanctioned because it makes them feel better about discriminating against someone.
I'm sorry you had to listen to this, I would find it very triggering as well. I wish they wouldn't let uneducated and uninformed people go on and say all these awful things. It just pushes us further and further back into the depths of stigma.

This sounds more narcissist than BPD in my opinion.
