My teachers treat me differenly b/c I have a mental illness. I don't know how to confront them Lately, ever since I got back from the hospital, my teachers have been treating me much differently from the other students, and have been coming off as condescending to me. It has gotten so bad that some of my peers have been noticing confronting me about it. I do not know what to do about my teachers or my peers. Can you help me?
Stay calm, is the first thing to try to do. Approach the teacher and be polite, most teachers like either after of before class. Make sure they are not busy. Then bring up your concerns with the teacher. Try to be as well spoken as possible and be straight to the point. 

With your peers, you can be more into the moment. Speak along the lines of, "hey, you don't have to speak to me like that." You know your peers, if you need to be more polite you should. Also, stay polite with your peers, explain the situation to those who listen. Important don't waste your time with those who don't.

An important note: You would not want to make someone feel super bad about it, because then they would also start treating you differently, but for different reasons.

Hope your situation improves
