Starting freshman football as a first year

I've never played organized football in my life, and I feel pretty out of shape. Conditioning starts in a week and a half and honestly idk if I'm ready. I know a lot of the guys doing it are a lot more athletic then me, and a lot of them are assholes too. From my knowledge, I only really have 1 friend I know doing it, and we're not close friends. Idk what to do because I really don't want to get bullied or made fun of by the other kids. Also on the side is conditioning as hard as people say?

If it helps im 14 5,7 140 lbs and I can only bench around 60.
