Should I report this teacher or do you think it'll back fire?

Today she stated clearly that she might have to fail me. Also this teacher isolates me in a group of four students, and tells me I can't give meds or I can't have two patients, and she says this infront of the other students. She also favourites this one girl and everything she does is okay and if me or someone else does it, its not. I have two more classes and I feel very down because of the stress and the way she's treating me. She also always use my mistakes as bad examples every class, and her favourite student always has the best examples even if she messes up. This has happened to another girl before too. This teacher bullies and student and try to isolate them. I feel like the other students are starting to ignore me and single me out because of the way she treats me and they all fear them.
