No, not out of the closet

I'm going clubbing for the first time, tonight, since going full time and for the first time in at least five months. It will be a party from one of the medical school years (the sixth) to raise money for their graduation. There will be a lot of people there who know I am TG, at least 50, minimum. And ya, it ins't a GLS club.
I know trial by fire might not be the best place to start, but heck, transitioning is brutal anyway! I'm not going to lock myself at home in fear of being read or from rude comments.
