I'm so sorry you had to go through that. I'm learning the hard way myself that professors are human to and they also make mistakes and do bad things. I don't know your exact circumstances, but I would recommend you drop the class. She has made the decision to be insensitive and callous and there's no reason for you to subject yourself to that. You wouldn't be letting her "get to you," you'd just be making the decision not to spend your time around her. That kind of behavior is not worth your time anyway.
Another thing you could do is go to the chair of the department and discuss your problem with them, preferably face to face. You don't need to chew the professor out in front of him/her, just say that you're in a class and you feel like you and the professor are really not getting along. Is there an office for students with disabilities on your campus? Are you in contact with them? I had an occasion once where professors were inadvertently giving me a hard time about one of my accomodations and I went to the OFSWD director on the verge of having a meltdown myself because the situation was stressing me out so much. He very kindly offered to communicate with the professors in question himself and explain why this specific accomodation would be helpful for me in this instance.
See there, now you have some potential solutions to your conundrum. Take a deep breath and say to yourself, "I have a way to fix this. It will all get better tommorrow," and then order pizza or something fun like that ;).
Good luck! Let me know how it all turns out.
