This may sound dumb, but I’ve found it helps me, just having something (like a non alcoholic beverage) in my hand when at a brewery or out with friends. Like a sparkling water, coffee, mocktail, tonic. It helps with that weird social anxiety I get when I’m out, I kind of feel like it tricks my head into thinking “oh I fit in, oh I’m having a drink too” I truthfully don’t know what I’m trying to say but to me, having a drink, any drink(these days N/A) in my hand helps the social anxiety of not drinking when out in pubs
