Hi newme2day.
Yeah, I too was "still worried about appearances" when I went to my first AA meeting many years ago. What if I see someone I know? What will people think of me? What if they think I'm crazy?
Meanwhile, during my years of drinking before that first meeting, I was so worried about appearances, that waking up on my neighbor's lawn half-naked, making a fool of my drunken self at work, making myself the main event at weddings (and not in a good way), being asked to leave a few bars...and to never come back, being taken to the ER on multiple occasions due to my passing out in public while detoxing a few hours after binging, vomiting and falling down in the street, and generally making a fool of myself were all okay with me.
The worst thing that can happen is that you'll hearing something that might save your life.
