I have some social anxiety too - definitely think it was part of why I drank - and sometimes going out like I did just last night - to a new place by myself (I knew some people there but did not bring a date) triggers that anxiety. Sometimes I wish I had my crutch alcohol to "help" me.
But I went anyway - drank a club soda - because I was solo, I had ample opportunity to talk to others and I met some new people - and all my interactions were pure and unaided by substances. It was a confidence boost and I know will help with future episodes of social anxiety .....
Congrats on 9 whole months!
