I remember my first meeting although i was very foggy that night, I walked in and shook the hand of the greeter and said I"m new.. that is all I had to say, the hands and hugs started coming my way. I still go back to that meeting now and again (I've since moved) and I always see someone I knew from so long ago and I feel
like a newcomer again.
The first days are hard, somewhat overwhelming but great! just do it and you don't have to be sick and tired any more. It really works. Listen to the slogans, One day at a time is still my favorite.
Best of luck take baby steps!
