Maybe Medical?

For about a year or so I have really wanted to become a psychologist and I still do. However, I've been thinking a lot lately about also maybe trying to pursue a career in the medical field. I know for sure that whatever I do after high school and college I want to help people. But since it is already the second semester of my junior year, college is approaching fast and I have to decide pretty soon about what I want to major in and where I want to apply to college. At first I was thinking about majoring in psychological development, health, and human behaviors all of which would help my chances of being a psychologist. But now with my growing interest in the medical field, I've decided that I would like to major in Health and Administrative Services. This major would benefit me both as a psychologist or a doctor or nurse.
