That sucks. Insurance changes are a pain, doc changes are a pain, and med changes are the worst (until you finally get something that works). You might try keeping a mood chart type of journal that tracks your moods, symptoms, and meds. I think there are even workbooks out there just for that. Then you've got a nice, neat black and white copy of your moods, meds, and symptoms that a doc can review without getting caught up in you having to present it - that the accuracy or inaccuracy of that process could be less aggravated by the human element (especially the bipolar human element).
I used to love it one when of my past docs would say "well, I'm hearing you talk about these symptoms but they don't really seem to be bothering you too much." Hmmmmm could it be because I'm hypomanic and nothing bothers me too much except stupid people.
Good luck dealing with the Vogons and their endless paper work and official procedures. Keep your own hard copy notes and wear them on a string around your neck
