Hi and thanks for the question which I’m sure will help others.
As stated you may only want to give your first name without saying you’re an alcoholic until you may feel ready, I would say that your new but again unnecessary.
In my area there are many discussion meetings and when I was new I was encouraged to say I pass then at the last moment I could say something I was feeling if I needed to.
This was to keep me focused on what others were saying and not to be preoccupied on what I was going to say. An expression that’s fitting “we learn to listen and listen to learn.”
BE WELL
