SAHM- I know exactly what you are feeling. I went to nursing school after my kids were all in school (i was 36). I did acute care for 4 yrs and, although I learned a ton and felt a lot of pride in what I did, I was always stressed.
I then took a job in public health, which I LOVE. The only downside is the 2 hr RT commute and the hours aren't many. Some days, I commute 2 hrs and work for 3 hrs
I just got offered a UR job locally, and I can name the hours. I am excited b/c it will be a huge learning curve (one of the things I love about nursing). BUT, I will not have pt contact. I could keep the public health job on the side (and the long commute)... I need to decide.
Anyway, nursing is wonderful for it's variety, and I agree that nursing in some people is "built in". You just have it in you to want to help people
Good Luck!!! Enjoy the kids while they're little.
