What should I do

Hey I am a m17. And I can’t get a girlfriend whatsoever I try.

So I go to school and we just had a prom, and I was trying to talk to girls. But not a single one even tried to talk back to me. Not even the girls in my friend group!

People keep asking me why I don’t have a girlfriend, and that I am not a bad looking guy. But I just seem to not get the interest of women.
