Hi! I suggest you try to talk to a school counselor about your problems. I know you are shy, but these folks are nice and want to help.

I don't know why these teachers are acting the way they are. All I can say is to try to hang in here. Can you meet with your math teacher outside of class or get tutoring?

As for English, who doesn't want to be praised for their work? It sounds like your teacher has gotten an impression of you that's not accurate.
