This is totally normal. The first year is really tough. Takes most people 2-3 years to start feeling confident in situations like weddings, bars, bbqs etc. A good indicator is barely noticing the booze in these places. If you're focusing on the booze, you aren't ready. no big deal,it takes time. also recommend AA - find a meeting you like and get a sponsor you also like. That, along with outside therapy ideally an addiction specialist, and one day soon you might realize that you don't give a shit what people think of you and that actually you are really great and there truly is nothing to escape from.
