They aren't real friends because real friends would never laugh at you or humiliate you! I feel sorry for you. I had similar problems at the gym. I'm really bad at sports due to a certain disorder I have. Stay strong. Try to ignore them if that's possible. And remember: You have friends online. We're here to support you.
Ohh i see they are just bad classmates, no friends, you and the others are my real friends, aandwoow i didnt knew that you had problems too, sorry to know, i'll think in ypu my friends and continue thanks
