If you have doubts, then leave it. Don't let others bully you into doing things. This is your life and your recovery.
I told everyone - but then there wasn't much of a secret - I'd become the neighbourhood drunk. It was kinda cathartic to do that, but I'm lucky noone took it badly - I really wasn't thinking about consequences back then.
These days, tho, I agree with Anna - recovery takes a lot of energy - use all your energy to get to where you want to be - then you can think about what you need to say and how you should say it, from a position of strength and surety.
