Hi anonymous0,

I'm sorry to hear that. It's hard to see a friend you care for going through difficult stuff.
I think it helps to understand that a pwBPD often lack awareness and
create conflict with Karpman drama triangles and will shift roles; persecutor, savior and victim. Often a pwBPD will be cast as victim and I think it's a good place to start with, learn about this dynamic and it will help with conflict with non-disordered people as well.
You may be cast in a role of rescuer or persecutor and the best position to be that has elements of all corners is moving to the center of the drama triangle; it's the most compassionate position. I understand that this is your BFF, it will help you if you don't take either polarized sides and you may want to validate your friend.
Hang in there.
