I'm another BP1 diagnosed 3 years into sobriety. I do not discuss my mental condition or any of my medications within AA period. That includes my Sponsor who used to make fun of people with BP disorder. I no longer use him as a Sponsor but talk to him more as a friend.
The bad part is that I really do not have anyone I can talk to about my BP1. Most people have very little understanding of mental disorders and there is a lot of extreme prejudice towards those afflicted. My Pdoc see's me for only a few minutes and he only seems interested if my medications are working and if any med changes are needed.
