Thanks for your thoughts, everyone. I'm supposed to see him again tomorrow and if I don't chicken out I might bring some of this up with him...

@Nammu, I didn't say I was "so upset," I just don't agree with the diagnosis of MDD. What was off-putting to me was not his skepticism of the bp diagnoses, but the reasoning behind it, which made me feel like either I'm not communicating by experience very well, or he just doesn't really get it
