There is a theme in your threads.....fear of being judged for being sober. I get it. But if I were entertaining going to a bachelorette party I personally would want to be extremely confident of my own ability to protect my sobriety. My desire to. My personal commitment.
You have already experienced the usual stuff....some care, some don't, some support you, some enable you. That's the deal. Your abstinence isn't contingent on anyone's support or lack of. I mean, that's how I see it anyway. For me, it's an inside job.
My concern isn't whether your friends are good or supportive friends. It's whether you can stand by your commitment not to drink. Friends may not always have your back, but you can have your own back.....
