You are def not alone, I am going thru the same, working nights, have no life, bad unit with not enough staff, bad management, aching body 24/7! list goes on and on. Start applying at some other floors ... that's what I am doing, we worked hard to get our degree, don't let one unit ruin everything, good luck! Going back to school is another option, NPs seem to have better shifts and don't have to deal with the big mess on the floor.
