I'm sorry to hear about what you are going through. I'm 46 and I was just recently diagnosed with bipolar 2 and BPD. I guess what confuses me is when I have an episode weather which disease it is. Then again I guess it really doesn't matter just as long as I get the right medication and therapy to help me through it. I can agree that it is particularly challenging because you just don't know which one you are dealing with.
