TheCommuter - I feel your pain. While the OP could have chosen his/her words more thoughtfully, it is his/her right to vent (complain?). My calling was (is?) opera. It is what I initially studied in undergrad and I belonged to Actor's Equity and performed. However, I am NOT starving artist material. So, because of a sincere interest in helping those in need, I left NYC, was a Peace Corps volunteer, and decided to pursue a career (which, for me, is a job) in nursing. I pursued my passion, public health, in graduate school and I am now qualified for low-paying jobs at county health departments. Great! I do my job well...heck, VERY well...but I do it for the money. I'll be back in a NP program in a year to attain a SPECIFIC skill set and, ultimately, make more money.
So, OP, don't feel bad. Many of the nurses that I have met don't love their jobs either (like many individuals). Nonetheless, we all have to keep a roof over our heads and food on our tables. As long as you do it with a smile and an open mind, well, what more can they ask of you. Good luck!
