I think you need to report this to the Director immediately. Not the Instructor...the DIRECTOR. When people start making racial remarks, that is 100% uncalled for. It doesn't matter if EVERYTHING she said was true, and EVERYTHING she felt was justified, it doesn't make a racial remark appropriate.
It is hostile, aggrevated, and if she is following you around like that, making remarks, I can guarantee you, she is capable of assault.
I actually thought I was going to read, where you said you checked your instructor's box for your careplan...this is another reason why you need to bring this up to the director, so it can be documented....that your care plan disappeared. Carry around a tape recorder with you (even if you don't tape your lectures). Turn it on right before you enter class and a few minutes before you leave. After you talk to the Director, if your Instructor has a habit of students "dropping things off", make sure you can physically hand it to the department receptionist or slide under her door before things start mysteriously disappearing.
If you can move your seat, sit BEHIND her in class...not directly, just anywhere behind her. That will make it very difficult for her to sit, stare, and watch your every move, b/c she is obviously a fruitloop. I also fear she may do something serious, make up a lie, and say she saw you cheating. If you are sitting behind her, it would make that viewpoint impossible.
Please do this immediately before something happens more serious. I am fearing that if she does lose her temper and there isn't a record of this, and she physically attacks you, it could put your place in the program at risk.
