I felt awkward too....until I quit hanging out with my old social circle
of excessive drinkers.
We no longer shared the same outlook ..booze was the common factor.
I connected to an AA group of mostly singles...we were all heading into
a sober lifestyle. We did all sorts of interesting things outside of meetings.....
Perhaps it's not so much about being introverted ..rather finding friends
who you enjoy being sober with?
Remember...we extroverts really need friends who will listen....
