I just attended a social event where I was very chatty and interactive and the center of attention, and now I feel very weird

I usually stay at home solving math problems and going to and fro to the office, and in general be by myself most of the time. I didn't know I was so smooth socially. I made everyone laugh, people (seemed to) actually like me.

And now that I have returned home, I feel paralysed. It's like I have been jarred. Its like I wont attend a social event for the next 5 years.
