I give you allot of credit for posting. It sounds like your anxiety is overwhelming, so just talking about it, even anonymously here, must be quite difficult.
At the bottom of anxiety is fear, and fear is a big part of why many of us drank. I think it might be beneficial for you to post about the nature of your specific fears. What exactly are you frightened of. There are an awful lot of people on these forums who have been successful in addressing their fears and you might find what is said beneficial. Just be completely honest about the nature of the fear and put a little trust in the group of drunks on this forum.
The AA program is remarkably helpful in addressing fear but if the fear is so overwhelming that it prevents you from working the steps then additional help might be a good idea. You might also consider phoning one of the staff from the residential treatment that you attended in order get a referral to an appropriate therapist.
I hope you find a way to address this fear. It must be overwhelming.
All the best to you.
