BHF , I'm with you big time. Good to know somebody else has those thoughts/worries and I am not alone. I live in the heart of the city and sometimes just walking somewhere to grab milk/dog food etc., I freak out thinking somebody is going to see me that remembers me from the 'old' days (me being in a bar alone, me stumbling down the street etc.,). The one bar two blocks down from my house I spent pretty much every day for the last 4-5 months of my binge for 7-8+ hours a day...in the event that I have to walk past there, sometimes I'll even put my hoodie over my head and walk by insanely quickly.
Even old friends that may mean well, I still just feel lots of shame being around them sometimes, or doubting their sincerity.
