Right on ARW!
The shyness will pass, I'm sure. You admitted your alcoholism to the most important person -- you (to thine own self be true). It will come in time, very weird to say at first, but for me it helps remind me. Also, you are among other alcoholics who have been there and done that. It's funny, in AA meetings we all have that common bond -- I know I didn't walk in there because of the good coffee!
Everyone else has said it, find a newcomer's meeting perhaps, get a sponsor (or even a temporary one), read the Big Book. The most important thing is don't drink, one day at a time.
Welcome to SR and to AA!
