Hello there! I'd suggest, even without a partner in particular, for you to still go to prom. Prom is a time where everyone hangs out with each other for most likely the last time, and it's quite memorable! There's a good chance that you will regret not going later in your life as I've seen with some I know, so I'd say it'd be best for you to have one last fun time in your early youth with others partner or not! That's what I'd say at least.
