That is a big fear for me, dx of personality disorder. I wonder if you are doing an inventory or EQ or association test? You will be really tough to deal with a diagnosis effectively... That would be really hard to come to terms with. What gives me hope is that there is so much we don't know about the brain, immune system, etc. I hope they figure out some way to treat your anxiety and get you back in shape. 
borderline is not one of the most stigmatized...self-injury is sort of a marker they've used for it, but not every self-injurous person is borderline. Pubmed might have some papers about it (probably shouldn't read list of expressions if you think you would be swayed to answer a certain way).
Good luck to you and please update if possible!!
