Ugh. Ugh. Ugh. I just read through your thread...
I can't believe that. Can you ask one of them to be a temp sponsor? Or, if rumor has it that she is there for social reasons, wouldn't everyone know that?
How about going to a different set of meetings?
You can do it alone. It is a little harder, to be honest and the nice part about a sponsor is running things by then because they will point out where you might be thinking astray. I'm sorry to hear about your experience. Jeez... Someone in my womens meeting last night said that she was on step 1 and can't move forward because her sponsor had surgery, 5 people blurted out "get a temp sponsor" without missing a beat.
