Hi. misskeena. I don't know if you were able to find an answer to your question. I'm a little confused about the differences between the two myself, so I can't really give a good answer. My official Dx (besides the MDD and anxiety), is "personality disorder, NOS," but I have been told that I seem to have signs of both BPD and AvPD. (Also dependent personality disorder)Hope you can find an answer.
