zoo, for what it's worth, my T is not a DBT therapist. She is a psychodynamic psychoanalytic therapist and as luck would have it (because I didn't know that my diagnosis was BPD at the time) one of her areas of specialty is BPD. She is a LMHC and MSW and also underwent psychoanalytic training (which is how I found her).
She's wonderful, very patient, accepting, and available between sessions by phone and now by email (although she may or may not respond because we are using it as a way for me to open up more rather than for immediate connection which I could have by phone because she provides her cell phone number).

I just wanted to post this because I know that DBT is recommended for a person with BPD and I wanted to say that sometimes what's good and what works is just what's good and what works. I think that other kinds of therapies are also good therapies for growth.
