After reading all of this, maybe it is a blessing in disguise. Some of the unfairness you speak of happening in the schools happens in the work place, not everywhere and all of the time but it does happen. The nursing field is heavy in politics, who likes you and who you know. If the nursing field is your only option then, take it as a loss and start over somewhere else. As I said, it is a who knows who type of field and if you fight the school, you will be fighting a lot of opportunites to pass. I don't think it is worth it to fight the school because you said yourself that you were lacking sleep. Nurses bounce around from here to there and someone knows someone. In your case, just pick of the pieces and move on. Pick and choose your battles. Save your energy for the bigger fights. Working nights and going to school during the day is hard. Maybe you can work prn, part-time , or try to get on days. You can do it, you can pass school. If you go over this stuff again, it will be a breeze. Try to get back into the same school.
