Best of luck to you Elpha..
Nursing is one place where you can use your brains, be creative, where science is really cool, where you can teach, where it is ok to feel deeply and laugh heartily, where you can make a difference in peoples lives every day.
Guess you can tell I really like the good stuff about nursing. As far as the frustrations go, I've had them in other lines of work. In my job, the good far outways the bad.
If your work situation gets bad, do your best, work constructively for change, and if necessary look for employment elsewhere, where you will be respected. There are so many options for nurses once you get a good foundation of skills.
If you can, try out some volunteer activities that expose you to nurses, (hospital, nursing homes, developmental centers for children in school districts.) Talk with nurses in different settings about what they do, and what makes them different from the aides and doctors. Check out some journals too.
Hope you find your way!!
