I'm about to break down and cry

I'm a highschool student, male. I know I'm gonna have to suck it up but It's really hard. I'm not being picky with girls either. It's just so hard to go out and be rejected all the time. I asked this girl in my grade if she wanted to go on a date, she's got a few pounds on her. She said no. Then I asked this slightly better looking girl in my grade. She said yes, but that she was in a relationship. I just feel like I'm worthless. So I'm fat, ugly, stupid, useless, and I don't even know why I'm here on this planet. I feel like I was tricked into living this life because I was so godamned dumb back in the day.
