Going from a Nurse to a Doctor

Hi! I am currently a high school senior applying to majors and colleges. I am really torn between Nursing or becoming a physician. As of now, I now I know that I will eventually be able to handle the rigor of medical school, but I am afraid of "burnout", the overall costs of medical school, and some of the personal goals I would have to sacrifice. If I were to pursue nursing and decide (after a few years of work experience) that I still want to become a physician, what would I need to do so?
