Help me decide what path to choose: PA, nursing, MD..?

So, I started out wanting to go to medical school for my MD, but ran into some health issues that took me out of school for a while, and as a psych major, I decided I didn't have time to finish all my pre-reqs. I will however manage to get all of the PA school pre-reqs done by my graduation in May. My current plan is to work as an EMT for two years and then apply to PA school. I also want to take a few more science classes in that time to boost my GPA and do other necessary things to help... Help me decide what path to choose: PA, nursing, MD..?
