Please take heart you guys. What made me realize I had BPD was reading three accounts of BPD sufferers on Quora.com who had each done DBT and each found it immensely helpful. The issues they described having (what DBT taught them about) was exactly the things I have been unable to do, and therapists have told me that as well, which means that that therapist who diagnosed me with BPD years ago was correct (and it isn't autism/Aspergers, etc.).

One account basically described a cure. The reason I believe she was cured was that she genuinely feels different inside. The anger is gone, and the depression is gone and she feels genuine peace inside. She says she still needs to pay attention to what she learned in DBT and keep practicing it, but it isn't like she's trying not to feel anger or depression and pretending she doesn't feel those things. Another thing to note is she had taken DBT multiple times (she started about 2 years ago) so it does take time. Her comments sounded genuine. I hope others on this forum (and me) can have the same success. If you want to read the accounts, go to Quora.com and search for the question"What is it like to go through Dialectical Behavior Therapy" (or maybe it is "what is it like to go through DBT", I don't remember).

I will look into DBT myself. I found at a website there are several DBT providers in my area, so I have a few to choose from.
