Psychology, theory, and history in nursing school

I am working on prerequisites and was curious. How much of nursing school focuses on the psychology, theory, and history of the nursing profession? I loved anatomy, loved physiology, and really loved microbiology. I also had psychology, developmental psychology, and an intro to nursing concepts class, all of which I hated every second of. If my interests are science, medicine, and learning about the advanced inner workings of human biology, am I in the right profession? I want to eventually treat and diagnose patients an a NP. Is there anybody who knows the nursing school curriculum who can fill me in? How much extra anatomy,physiology,and biology do I get to learn in an RN program. Would I learn more as a Biology undergrad?
