OP, you are not alone, and it's not just the ER that can affect nurses that way. I am well and truly burnt out, and I thought going back to school would help things, but really, no. I have my BSN now, and I couldn't care less. I felt no joy in obtaining it. I'm well and truly looking at leaving the profession. It's been an interesting 20+ years, but now I'm ready for something different.
