My party went really bad, for some reason I couldn't hook up with the girl I was grinding on, and one other who was too drunk. I really hate being single and lonely and need serious help here

I feel under confident and am currently cursing myself so much. It really sucks I have no idea how to express that, I can't have gone 20 years without a girl; my parents would find it absurd if I told them this, it's that bad
