I can relate. I feel everyday is tough for me at work. I've just started going to a psychologist to know if I have autism as many suggest, but with all you wrote I can relate.

When kids in class start yelling or if too many try to check their homework and they surround me, I start feeling pressure or confused and feel the to move around to block the overwhelming, yet I can't and have to finish if I want things to go back to my control. I also take insults very personal. Sometimes kids are just making jokes or playing around, but I don't know where the limit line, I panic wondering that if it's something that requires a punishment and I don't apply it, I'll be doing a bad job... So I get very confused on what I should do.

The good thing is that I don't have a specific classroom, I give three classes per week to each classroom so I can cool off. But how I wish the principal or other teachers see that it can be very difficult for me to do those things and I try my very best to always perform a good class, yet they don't recognize or see this extra effort. Although, our old principal, just before leaving did call me to the office and told me he was very happy with my work. That cheered me up. I don't have a diagnosis obviously, and people tell me it isn't necessary, but if people knew about it, I'm pretty sure they would at least try to understand.
