What to do? What to do?

So.  I don't want to feel as if my bachelor's degree (Business Administration - concentration Operations Management) was a waste of time but I don't particularly enjoy it.  It probably doesn't help that I denied the career path that I really should have taken...medicine.  Through many discussion with my husband and years of watching medical mystery shows, crime scene investigations, and animal rescues, I've decided I want a career change.  I realize I have to go back to school and to be honest I secretly enjoy the idea of going back to college. 

Here's my dilemma (a dilemma all freshmen in college face): what do I want to do with my life?  When I was younger I was hooked on Unsolved Mysteries.  Any show that had to do with solving a murder or crime through medical science I was glued to the screen.  Knowing that a crime could be solved because of the contents of the person's stomach or from a carpet fiber amazed me to no end.  And part of the glory of it all is that you are speaking for those who no longer can.  Most recently I've gone the opposite direction of death and enjoyed the idea of becoming a labor and delivery nurse or a pediatric nurse.  I've also read a few books on midwifery.  Walking couples through what is probably one of the most special moments of their lives is awe inspiring. 

So?  I'm torn.  Do I become a nurse?  Or do I become a forensic pathologist?  I hope to start school at the beginning of next year.  I obviously need to make a choice by then.  Either way, I know I would enjoy what I was doing.  I am also pretty much guaranteed to never be bored at work.
