Welcome, Daria. Glad you joined the May thread.
Each day is a challenge that is different from the one before. Your plan sounds like a good place to begin. I too have (and do) struggle with how to handle those situations where I ordinarily would have been drinking around other people. As far as my family is concerned, there isn't a single one that's saddened or let down that I'm abstaining. Friends are a little bit harder.
I agree that it's nobody else's business but I also see why we have to prepare for how to handle the inevitable questions and turning down the offer for a drink. Avoiding certain situations in the beginning days is crucial for me. I'm only day 12, but that is a victory cause each day is what we are trying to stay sober in. Not "forever" but "today."
Glad you are here with us.
