Should I get checked for BPD or a similar illness?

I might be over reacting, and I would like to talk to someone else before I ask my doctor, but I check off for 5 or 6 of the 9 DSM IV Diagnostic Criteria. They are minor symptoms and only occasional, but enough that I would like to know if I should be worried. Even if it is not BPD, I know BPD symptoms could be linked to other types of illness. If you know enough about BPD, please offer advice on what I should do.
