Dang it, that sucks. Here you are doing something good for yourself and someones already bugging ya about it! Next time she calls, I'd say "wow you are so nice to be worried about me, but honestly I'm kina easing my way into this, and I'm not always sure until right before if I'll be able to make the meetings or not. I look forward to seeing you if I do go though" Start it with something nice, and end it with something nice, but get your point across. Congrats on AA though! Keep up the good work!
