dear jack,
i am sorry to hear that you were misunderstood by your friend. but you should not be silent about this case. first, you can go and talk with your friend. why not tell him the truth? maybe he would unstand you. then, it's a good idea to talk to your parents or other friends about your trouble. it's important to let out your feelings. last, i know that you like to do some sports and you can ask some friends to play sports with you. just relax and you will find a very way to solve this kind of thing by yourself.
best wishes
yours
