A lot of people who meet criteria for one personality disorder also meet criteria for a second, or possibly more. I have been diagnosed with Dependent and Avoidant, and I feel that BPD fits too, maybe even better or a more complete description for me. All of the personality disorders are really descriptions of traits that are patterns in your life. They aren't going to be comprehensive descriptions of you, but may show what kinds of patterns are problems for you. And some of us have more than one overlapping pattern. I would guess that we all do, since people are pretty complicated.
