Last Saturday I went to a local nightclub, approached a girl at a dance floor. She was above average in terms of looks, had 2 female friends with her. I went to her, we started dancing she seemed a little irritated, then all of them, she and her friends started laughing looking at me, she started dancing even closer to me, and after few seconds ran away to her friends to have even better laugh. I was devastated and went home, I knew I was ugly, but damn, this crushed me.

Maybe someone could tell me how to overcome and forget that?
