Please try hard not to over-think the situation. Try hard to relax and don't worry about messing all of this socializing up.
First of all, two days in a row of socializing, after maybe not socializing to that degree, is A LOT. Distract yourself by doing something you like to do alone for a day. Give yourself some time to adjust to all of this socializing.
I am sort of a social person by nature (I'm NT), but as I grow older, I relate very much to my son (Aspie) who gets worn out by too much socializing. I am exhausted after certain events -- parties with people I don't have much in common with, actually any socializing with people I don't like. I want to minimize that kind of socializing as much as possible, and after I do spend time this way, I really am tired and need to unwind, alone.
Do not worry about whether you've done the right thing or not. You are socializing, and that's a good thing. Pay attention to the few times you make mistakes socially, and try to eliminate those mistakes as you socialize further. But don't obsess over the mistakes. Trust me, truly social NT's don't worry over their mistakes, and yes, they do make mistakes too.
