HI Georgie
I think most of us felt out of place when we got back into socialising.
I took a few months off from any socialising involving alcohol and I built up my 'sober muscles' by going on coffee dates,. picnics, museums art galleries - anything where I was unlikely to find large scale alcohol consumption.
when I knew I could handle anything and anyone I stopped being so cautious - but I found a room full of people trying to drinking themselves stupid isn't really my ideas of fun anymore.
I have a LOT of fun now, I'm not self conscious about beign a non drinker, and my social life is the best it's ever been...but not much of it happens in clubs or pubs.
