Any chance?

I have a crush on this guy, John. So John is on the football team at school and I manage it with a few other girls. I'm not exactly popular, and the other girls are and are very talkative with the team. This one girl, Kailey, was talking to one of the other managers about a party or something and she was talking about how her and John got close and cuddled and stuff and now I feel really shitty cuz I'm jealous and feel like no guy would ever pick me over the other girls at my school and like I will never really have a chance with a guy.
