Is this normal? Does anyone else feel like they do this too?

I like to be around people don't get me wrong. And going out is a ton of fun but for some reason every single time I go somewhere I have to escape to a bathroom. I would cancel a plan if there wasn't a place with a sink and a mirror where I could splash water on myself or just sit and take a breather or something. I have to do this every couple of hours and sometimes even if I'm only around two other people or something. My friends say they think it's weird because I just randomly disappear for 10 minutes when I do it. Is this normal? Or am I super weird for feeling like I have to run to a bathroom to feel better?
