Hi, Christine and welcome to Psych Central!
I used to have BPD, but found a different kind of therapy to be helpful (Dialectical Behavioral Therapy)--and working though my anger toward my parents.
I'm sorry you had a bum therapist and am glad you're seeing your way past her. It takes skill to deal with folks with BPD and evidently she wasn't good at it.
Please don't lose heart. I'm glad you're here.
