Hi MarysLove and welcome to the group
We understand the challenges of facing the facts about BPD. It is a journey to that acceptance and to figuring out how to move forward after accepting that the mental illness BPD is in play.
It sounds like your daughter is able to be employed? Can she hold down a job ok, and does she live on her own?
The blame sounds very familiar, and can be typical for a pwBPD (person with BPD). She blames you and her father -- are you two married/together? And do you have any other kids?
Lots of question, I know -- just getting a better sense of your situation.
Even though it make take time and may look different than you had wished, there is hope to have a "good enough" relationship with a child wBPD, though it can be challenging.
Looking forward to hearing more;
