Just go. I went dateless when I graduated, just passed the time having fun with friends. I was in the same boat as you two years ago (shy at big events, but had a tight circle of friends), and I ended up extremely lonely since I went into trades straight out of high school, and barely hung out with friends who lived up their last summer before university. Now I'm pissed off with myself, dealing with slowly dying inside and putting on a fake smile to stop from telling me to cheer up. Hell, I could have died today at work, and probably wouldn't have cared. Back to the point, I never regretted going to my prom, but it just never had that unforgettable spark for me.

Prom might be your last chance to cement your connections to the friends you have. It didn't really work for me too well. Sorry for the morbid tangent I went off on, but that's honestly how I felt post-grad.
