How do I get out of prom?

Well, prom season is around the corner (all the local radio ads are saying that at least) and im bummed. I dont want to go now. My parents bought this bundle that included a ticket. Back when we got it, my friends and I were all single. We were all gonna hang out, eat food, and go home. Now, both my friends have girlfriends who they are taking. I feel like im one of the only people without a date there and have no desire to be there all alone. Tickets were almost $100 though. How do I get out of this?
