That sounds challenging. I've never witnessed anyone get called out for being in the "wrong" meeting, but when you go to a new meeting for the first time, you never know what you're going to get. I went to a small meeting once in a town that will remain nameless where the topic was frustration over someone taking your wet clothes out of a washer at the laundromat.
In terms of your recovery, in the end it's whatever works. Whatever can take your life from struggle and misery to calm, strength and joy -- go for it.
