I don't think you need to do any True Confessions right now unless you feel good about that.
I didn't "come out" to friends, only my very closest family, and I didn't tell them right away - it had been many months of not drinking before I mentioned it to them. Of course it gets better in time and I'm easily able to go out now and be around alcohol. A simple, "I'm not drinking tonight," works once some time has passed.
I prefer a night in after all the shenanigans I used to be up to on a Saturday.
