Love that you have a plan. Lots of solid pieces there.
Your use of the word "pride" worries me a bit, though....that emotion can cut both ways and I know led me to participate in stuff I knew I shouldn't sometimes, rather than keep me focused on behavior that would truly make me proud.
Also from my experience, a hyper demeanor reads as excitability, which is a flag for me. That sensation, when I realize it, or when it comes across along the lines of agitation or a twines to others, are big signs something is disturbing me.
I also strongly echo the "don't go" option if even a tiny thought crosses your mind that makes you uneasy. Not just because of actual drinking, rather more because of emotional jeopardy, I will not be attending the annual Thanksgiving day bash our restaurant owners host.
Good luck.
