I can really relate to what you are saying. For me, I just won't let myself go to the bar anymore. It's just not fun going somewhere built for drinking, where everyone is drinking, and drinking is the primary point (if not the ONLY point).
And, of course, it's a threat to my sobriety. When I'm constantly around other people drinking, I begin to think that it's "normal" to be drinking, and that there is something wrong with me for NOT drinking.
Maybe you should think about taking a long break from going to bars? I can say that simply making that decision lifted a huge weight off of my shoulders.
