Chardonnay and Marjoram, it's really hard to do this without support from people surrounding you, especially if you're both dealing with others with addictions. Weasel has talked about this too. No easy answers on how to deal with it.
You may have to just walk away from the offenders for a bit, recharge, do something that will alter your mood and help you cope. Watch something that will make you laugh. Read something that helps you to escape. You both were wise to come here and vent instead of picking up a drink Try to imagine how proud you'll feel if you resist, and how much more stressful it will be dealing with these same situations drunk. Hang in there!
