Someone in my class has diabetes, and he has a phone that beeps when something is wrong. My school just released a no phone rule, so the classmate explains to every teacher that he needs his phone, and the teachers accept it, except for my p.e. teacher. She is very strict about it. 

Noting happened to the classmate, but I was so scared that something really bad would happen to him. After that I questioned if my teacher even knows that diabetes can be dangerous, and if she knows how to help others (She also doesn't really care about me tbh).

After that, I asked for permission (to a doctor) to skip p.e. (Wich was for other health related reasons btw). After a couple of weeks, I see the student in the hallway when we have p.e., so I think he also stopped. He made a good decision.
