With your excellent background please consider applying to med school or pharmacy school. If you can afford it, med school offers the best opportunities and variety as well as more pay. Do not be discouraged, nursing is a grind, they can call it a profession all they want, but it is a lie! The stuff you are forced to endure and put up with, consider yourself lucky that you quit and didn't continue. Read all nurses and see how many of us are struggling and unhappy and burnt out, how many of us have been and are being abused and mistreated by the hospitals and some nasty psychotic patients.
But don't throw away all the education, truly consider going to med school. Even if you need to go back to take a few pre med classes such as biochem, calculus, physics if those weren't part of your nursing program. Looking back, I wish I had done this when I was a new nurse and maybe I wouldn't feel as sad, trapped and helpless as I do. They say nursing has so many opportunities I don't see that. To me finding a good fair decent nursing job is looking for a needle in a haystack and only a few lucky people actually find a job that doesn't demoralize and destroy their emotional and physical health.
I feel trapped and have been a nurse for almost 20 years and what do I have to show for it, injured twice from work, stressed out and burnt out to the point of needing medication, HTN and worried about hep C exposure which is much more contagious than HIV. Granted it can be treated and for some people you can be cured of hep c but not everyone.
If you go back to med school you will have greater options and if you choose a specialty vs family practice or internal medicine you will have much better working conditions than you would ever have as a floor nurse and also almost no risk of back/neck injuries or HIV/hep C etc, unless your a surgeon. Family practice/internal medicine is still a grind because most doctors are now under the hospitals who work them to death, just like they do the nurses. Specialists still have better pay and most importantly autonomy. I find it so disrespectful that hospitals could set up a system where doctors are supposed to see a patient every 7 minutes at a clinic, turning medicine into a assembly line, just like hospital and nursing home nursing already is.
But if you go into a medical specialty you could still have a good job helping people and not being rushed and stressed out to death on the medical assembly line trap that is healthcare in America today!
Sure you could join the many nurses rushing to become NP's to get away from bedside nursing, but you will still be stuck in the assembly line rat race that is hospital clinics and poor working conditions. With your great college GPA and background shoot for the stars and go to medical school. Just keep your student loans as low as possible and stick to govt loans if you can. Avoid Sallie Mae like the plague as it is a private for profit known for screwing people over!
I wish you the best and a brighter future than being a floor nurse!
