It could be anxiety in one for or another. I get anxiety in high-pressure social situations sometimes (mainly because I work from home a lot and don't get many opportunities to socialize offline anymore).

If physical activity itself doesn't help, try something with a strong mental or emotional component like martial arts, rock climbing, or dancing. You just need an outlet for whatever you're holding on to.
