What should I do ?

Hi, so here is the story.. Basically, I was playing a football game [non contact American football] and then someone from my class who was in the same team told me that I am rubbish at the sport. I injured my thumb: my thumb is broken, and he said that my thumb is broken because I am rubbish at the sport. He later told me to get lost, jump a cliff and that everyone in the team is better than me. So I am here on Qfeast to ask if you can help me.
