In my 3+ years of sobriety, I've gone through feelings like this a few times.
Why would anybody want anything to do with me or even to be near me?
I know it's an irrational feeling, but it's there and it's real. There is absolutely no reason for it and nothing in particular that prompted it. Nothing is different now than yesterday or the day before. I've participated in service work and AA fellowship as always.
Today, I have tools to use. The most important tools I have are (1) don't drink (2) remembering that This Too Shall Pass.
It always does.
My schedule for today includes 2 sponsee meetings sandwiched around an AA meeting plus a visit to my Mom. I'll be just fine as long as I don't drink.
