Y'know, I think most people get cold feet right before making a significant decision in life. I'm not a nurse yet, but every time I have second thoughts about investing the required time, money, and energy in a nursing education, I remind myself why I chose nursing in the first place. It might be helpful for you to do the same. For instance, maybe the medical field interests you, or you want to be in a career that will make a difference in the lives of others, etc. Yeah, it's gonna take time to get the experience/ education you'll need to be a great nurse and you'll probably work alot of long hours, but if this is a career that you'll love and that will fulfill you, go for it!!
