Hi @Zofloramummy,
Congratulations on two months! I really relate to your story, I think it shows how something so socially acceptable easily becomes a coping strategy and how quickly it can spiral from there.
I think @MissConductUS offered some great advice. I have to be honest and say I am still at the stage where I am selective about who and where I socialise as I know that certain people and places have the potential to be triggering for me. I am sure in time I will have more confidence to deal with different situations/ people but my sobriety isn't worth risking at the moment. I would agree with @MissConductUS about telling people on a need to know basis, but I would add it might be worth telling close friends (only if you trust them) who you usually drink with as that may help with the social situations.
I really hope you get the support you need.
