You can be out and have a social life while drinking alcohol free drinks. I've been drinking alcohol free beers 90% recently, most of them aren't that tasty but a few of them are just as good as regular beers.

In my experience people don't care if you drink pints of vodka or orange juice, as long as you're physically here and engage socially. It's like being vegetarian, some friends might look at you funny for a bit but unless they're complete morons they won't actively judge you
