Yes, there can be a lot of people at an AA meeting on a holiday as that is typically the hardest time for many who are challenged and are trying to "not" escape through alcohol.
The take away from that is to see you are not alone with the struggle.

I am sorry childofchaos, it sounds like you are experiencing a cycle from being triggered, I know what that is like as I can struggle with them myself. This is when you need to be extra patient with yourself and find things that help you self sooth that don't include alcohol and self harming. I know that is a challenge but I am very impressed with how well you have done in spite of being so badly triggered. It's important that you are validated for the "positive" things you accomplished in spite of this significant trigger, the control you "did" manage to have is progress.

I do know the desire to go back to bed and curl up, experience it myself. But you did not do that, you were strong and did well and you can make gains on that.
