Jen- it took me years to go to AA. The shame and horror-all those people questioning me, giving me a hard time. Absolutely untrue. I sat at the back-no one bothered me. A few people smiled and said hello but that's it. Nice people. All with an alcohol problem-they will not judge you, they will welcome you. It is VERY anonymous. All are their for the same reason so I wouldn't worry about seeing them on the street or office. I've come to believe it was my addiction that feared the place so much.
If nothing else try to get a decent meal in yourself.
