I am so sorry to hear about everything you are going through. I can relate to the feelings towards nursing that you have right now. I've been a RN BSN for 8 years and feel like I've tried it all. I, too, got to the point where I thought of quitting nursing because nothing seemed to bring me joy anymore. I even bought a book about changing careers!
I remember vividly being at work one night feeling like I was going to explode. It was a quiet night and all my patients were "easy" so I had some time to think. As I sat in my chair, I reflected on my courses and practicums from nursing school. A light bulb went off when I realized I had the most fun in my community health courses. After that, I looked up positions in that field and came across a position in corrections and I truly enjoy it. Maybe try doing something like that. Try to remember why you got into nursing in the first place. I also highly recommend going to counseling as Nurse Beth suggested. It really does make a difference. I wish you and your husband the best.
