I Am Graduating High School This Year

Why is it that now, in my second semester of senior year, I'm feeling so conflicted over prom? I never even cared before. But now it feels like, since it's coming up, and it's my last chance, I really want to go. And I'm told if I don't, I'll regret it in the future. But I've never even dated and have no one to go with! This, combined with college and a few other probably silly things, makes me feel so awkward and different, in an uncomfortable way that I haven't felt for about a year and a half now. Ugh I'm not expecting anyone to respond to this and I'll probably delete it but I just feel like I wasted four years compared to everyone else and the whole thing is making me uneasy and somewhat stressed, I just wanted to say...
