Sounds to me like you are doing great. Other people are a nuisance thought aren't they?
I am a pretty self-conscious person, but take a lot of strength from this phrase, which I first saw in a SR post or signature...
"What other people think of me is none of my business"
I went to a big party this weekend and stuck to lime and soda ( which looks pretty much like a large G&T or V&T to anyone who is interested ).
I drank about five or six in the first couple of hours and wondered if anyone was quietly observing and counting my intake. The bartender and I knew what was in my glass, and that is all that mattered to me.
To others, I have found that saying "I don't drink" is enough.
If pressed, I encourage my questioner to tell me all about why they do drink alcohol.
This goes on until one of use gets bored or needs another drink.
Best Wishes
