Hi Indigo,
I had to fire my first sponsor because of some inappropriate behavior and understand what you are going through. I've had my current sponsor for almost a year and am much more comfortable with him. Get another sponsor. These folks have no place giving you medical advice or countering your physician. Where I come from in the AA world, depression meds and the like are recognized as ok as long as a dr. is prescribing them, they are taken as prescribed, and the reasons for taking them are legitimate. Sounds like you just got a bad sponsor there.
Is there any way you can leave the company of these jolly fellows and go home? Maybe you could go to a meeting you are comfortable with in your home town and start that process of finding a sponsor that has what you want.
Hang in there my friend. Had a lot of the same feelings a while back.
Jup.
