There is a teacher that dislikes me for absolutely no reason. I never skip class, i am always active during his class, i have never cheated on one of his tests, i never talk to him disrespectfully and i dont disrupt his class. Somehow he manages to act like he doesnt like me and he insults me in front of the whole class. For example, a couple of days ago i excused myself for not being able to come to class for the next 2days because i had a really important doctor’s appointment and i had to leave town, but he started screaming at me and making me feel bad for having to see a doctor. While i was away, he mocked me in front of the class. It’s not the first time he treates me like this and i’n sick of it. What should i do?
