There are a few people on here that were not told of their diagnosis. My guess is that there is still such a stigma with BPD they think it is better if you don't know. Personally I would be pretty mad if my doctors did not share my diagnosis with me. Knowing what you are dealing with is half the battle. I know for me there have been changes (small but still there) since I was diagnosed in September. I imagine once I start my DBT I will see a lot more.
