<human>: A few months ago I hurt my back and missed a lot of practices studying for midterms for my high school team. I really fell behind and thought it would be best to become a manager and help out the guys. I motivate them, fix equipment, help the head coaches with various things, and then today I found out that one of the assistant coaches thinks I don't help the team at all. That I might be hurting them. When I found this out I was on the verge of tears, I've given up my entire social life to still be apart of this team and to help out. The head coaches always say thanks and stuff, but it really hurt a lot to find out this coach doesnt appreciate anything I do. I'm really at a loss Reddit, do I stay and "help" the team? Or do I quit? Everyone loves me on the team, I can usually calm them down when they are faced with a tough workout, encourage them mid workout and make them laugh to keep spirits up. But apparently that's not what I'm supposed to do.

Can you give me a shortened version of the text?
<bot>: Became a manager, worked my ass off helping the team. Find out a coach thinks I'm a waste of space.
