I wonder if there might be a different meditation group that you could attend.

I ask because it sounds like your friendship with the facilitator is interfering with the class for you.

Here is a question: would your reaction to her enthusiasm have been different if she wasn't a friend, hadn't known what happened to you?

I know that she is allowed to compliment the art teacher. You however are allowed to have the feelings you have. You do not have to stay in the class when something upsetting happens, or when the teacher seems to be withholding from you.

I wonder about the possibility of another group because it sounds like your experience with meditation overall has been good, but in this particular class things have started to go downhill.

Maybe you don't have to lose meditation support entirely because of how one specific teacher behaves?
