What To Do If Your Gym Teacher Publicly Humiliated You?

if the things are the truth and have bearing on your education -- you suck it up and get over it.  otherwise, you can try complaining to the principal and/or changing schools

Sounds like you are blowing this out of proportion. Nobody cares. Everyone is too preoccupied with their own insecurities to be concerned about yours.

Just how did the gym teacher humiliate you? And who is "everyone" and what did the gym teacher tell? Teachers are supposed to communicate about students so they can help the student. They are not supposed to tell other students about a student. Your post is so vague that we really can't help. 

Sorry I didn't really address your issue. Your gym teacher doesn't sound like someone who commands respect. (Or deserves it). 

When I was in high school Coach Wojack, a retired marine, was the hall monitor. 

Groups of kids were on both sides of the intersection, and I just waltzed through them. He started to yell at me to wait for the bell when the bell rang. I shrugged my shoulders at him at kept walking. He jacked me up against the wall in front of all the other students and taught me a lesson that stayed with me all my life. I didn't whine about what a victim I was. I was a smart-*** punk who got a lesson that served me well. A couple of years later when I got stopped by a Chicago cop, I was all yessir, nosir, and respect for authority. If I wasn't cured of my attitude I would've received a beating I'd still be recovering from today.

It's a shame that the snowflakes made discipline and public humiliation into a federal civil rights case. Kids today often have no respect, and are rude, entitled little brats that are in for some harsh lessons about how the real world works.

Liberals have ruined society.
