Hello,
Congrats on your sobriety. While it might not have helped in this particular situation, as I think you were at home, I have found that when going places where drinking is to be expected, that it helps to have an escape plan; i.e. park on the street so you are not blocked in, have an excuse ready to pardon yourself if it gets to be too much for you, have a sober friend to call, etc. I wish you well.
