Should I go to prom?

So the prom ticket deadline is coming up and I'm not sure if I should go to prom. I'm not poor or anything but $150 + my prom dress seems a little excessive and I don't even have a real group of friends to go with. But people at my school keep saying "oh it's our senior year! We can't miss prom.".. idk anymore. All my friends are fake, they ditch me every single day, hangout together without inviting me, and I can't imagine how prom would look like. I mean I want to go for the memories since I never went to any of the homecoming dances, but the thing is what memory would I make? Sitting at a table alone while everyone is dancing and taking pictures with each other? I just... I need advice should I go or no?
