Search Results: getting a girl to dance with me

When I was a senior in high school (last year), I had to go to my senior year prom by myself. I planned on asking one girl, but she told me she didn't want to go with me. I tried to ask another girl and she said the same thing. I planned on asking a third girl, who was having trouble getting a prom date, and she decided to go by herself knowing that I wanted to go with her. She even called me "ugly and not worth her time". I planned on asking two more girls and they both turned me down too, both saying that I wasn't attractive enough for them. I was depressed and on the brink of crying (which is major because i'm not the type of guy to cry about stuff) and not go to prom at all, but my friend convinced me to go because "it would still be a fun time". Well, when it was time to slow dance, no one wanted to slow dance with me so I sat out and wallowed in self-pity and blamed by genetics (which was the reason why I didn't get a date). To this day, this still affects me. I don't approach girls because I already know that they don't want to date me. Should I let go of this thing that happened to me?
