Should i go to med school or for nursing?

Hi, I'm going to college next year. And I'm not sure yet which path to take. I'm very smart and I enjoy being in themedical environment. I am already directly admitted into the nursing program at West Virginia University, but I was talking to an intensive care nurse the other day (I intern at a hospital) and she told me that I should just go to medical school. I'm young and she said that if I'm already planning on getting my masters degree in nursing which I was, that I should just go to med school. Its only a few years longer and it pays much better plus you are more of your own boss. Money is definately important to me. I want to live. Comfortable life without having to worry, I have hobbies that I would like to continue and I want to be able to provide for my family when I get older. I heard that medical school is super hard but I also heard nursing is too. I guess I'm scared because med school is way harder plus I would have a lot more debt. Which path would you Choose? Why? Please help and if u are an anesthesiologist or a nurse anesthetist, please tell me what you think about your career. Thanks I appreciate It!
