Ohhhh, Thomas. I so want you to go to that meeting! In my rainbows and lollipops world, I envision you finding peace, fellowship and acceptance there. But... I know sadly it isn't always that way. Can you spy on the attendees from your garden and pick one that you can confide in? Or is there someone in the other meetings you attend that sometimes frequent this one? That person could tell you what to expect and help you make a decision.
Shame is internalization of embarrassment or remorse. At least that's my take on it. Is your family embarrassed that you are in AA? Why?
