Breathe. DO NOT DRINK.
AA is made up of all sorts of people, including some odd balls. Don't take it offensively. Give it time. Until then, do you have numbers of people you can call for support?
We are here with you. You are so proud of all you have accomplished and we are proud of you too. Don't let other people who are acting inappropriately ruin that.
Tight hugs and much love coming your way!
