I, too, am sorry this is happening to you... Please try very hard to take your time, breathe, calm yourself as much as possible. Catatrophizing (or the appearance thereof) will NOT get you where you want to be. Remember, noone else knows all of YOUR situation and feelings, and even if they know a lot, they will judge you by how you are handling the current situation, stress. You do have rights, but must try and assert them as calmly and matter of factly as you can, thus also showing that you are able to do this. A break in coursework might be necessary. Make sure you get credit for what you did, and have the option of retaking the same class or choosing another for that credt.
