One of the psychologists I went to admitted he just put major depressive disorder because he considered that the least "labeling" diagnosis. Once I when I asked about BDP myself, my T said, "that's not you, you don't cause problems." and she said it with a bit of emotion in her voice. Never asked again. The thing is, when I go to my psychologist and T, I act cooperative and I do not disclose so, so many things to them. I guess I am afraid of labels too. It is silly that medical professionals look at certain mental issues in a negative way. All the labels are approximations anyways--a point of discussion. They don't have brain scans or genetic tests for BPD. Though it can help you discuss some of your issues if people did not look at it as a good or bad thing, just a sort of starting point for conversations and treatments.

As far as I am concerned, you may never know your true diagnosis or if it is just confusion and low self esteem. I don't think psychology is like that. Maybe, someday, they will know more....
