I went with friends. I think most of them didn't have a date. I honestly can barely remember bc I didn't really care who had dates ? but we all went to a restaurant together and then just hung out and danced at the prom. I don't remember feeling a lot of pressure to have a date and I wasn't looking for one. I was more interested in a chance to dress up, eat out, and dance
My advice would be to find others who want the fun friend group experience and do what you enjoy. Even if it's not what others are doing.
