Maybe getting into a mindset that isn't so easily turned negative. For instance, the one you posted about. Is training really a "social" situation? No, it's work. It's not something you'd choose; you have to go. So did everyone else. Not social, not something to get anxious about.
And speaking of everyone else, you said they were a group of people you didn't know. Didn't know and probably won't see again? So why is their opinion or thoughts about you so important. The easy answer is, "They aren't," but they obviously are for you.
So you might want to work on that. Beyond my abilities, but perhaps counseling would help you.
