I have a masters and am a licensed marriage and family therapist (LMFT). Same wholistic approach. In fact, I minored (27 hours) in social work. I can remember that restless feeling in school (you get over that as you realize listening quietly is a tremendous help). I'm very good at what I do, and I still do it informally, but I am finishing up a degree in nursing.
For me, nursing has been a lifelong dream I believed I could not attain for a variety of reasons. Not being able to find decent employment as an LMFT pushed me toward nursing school
. I love it, I'm having a blast. I believe both professions tap into the same part of our personality: helping.
Practical considerations are important: nursing probably has more flexibility, better potential for advancement and more job security. Also, you can give nursing care to your family and friends, but you get into serious trouble (emotionally and relationship-wise) if you try to "help" family and friends even with counseling and support--this must be left to the disinterested third party professionals.
Pay for nurses is much better overall, and there are more jobs out there for nurses.
Just my two cents. I'm doing both, which I think is also very cool.
