Pharmacy or Nursing: how do I know which one is for me?

After completing my undergrad degree in Poli Sci, I decided that I really wanted a career in the healthcare field. I did some research and saw that maybe Pharmacy was best for me and have been working at a local pharmacy for over a year now. So far, it's been going well. I also went back to the local CC to finish Science pre-requisites. Not too long ago, I had my first baby and saw firsthand how one nurse can make all the difference. It seems like everyone in my life sciences courses are headed into Nursing and now I'm beginning to question whether I should also. I feel like I've been in school forever and Pharmacy school is another 4 years to add to that. Nursing would only take another 2 years at most and would pay not significantly much more different (at least so I've heard in CA)? Not to mention the loans I will rack up for pharmacy school versus the significantly less amount for nursing. Where do I go from here to make sure I am headed in the right career path? I have a family now and can't afford to do anymore self/career-exploration. Is there anyone out there in either field who can give me some pros and cons? Anyone been in my shoes? Any advice/guidance would be greatly appreciated.
