AAaahhhhhh!
Immediate question: Do you HAVE to go?
And if you HAVE to go, do you have to stay the entire time?
I'm sure you WANT to go, but do you have to?
Just puttin' it out there - I couldn't be in or around bars or people I drank with for quite a while (more than 6 months, closer to a year) but that's me.
If you really have to go, just a suggestion...keep the phone numbers of anyone/everyone who's supporting you in your sobriety. Whenever you feel the urge to give in, they'll only be a call away. Best wishes.
