Seriously considering getting out

I am seriously considering leaving my position as a RN in a school. This is my 4th year in the position. I am even taking classes to become a certified School Nurse in Illinois.

I am the only nurse in my district and feel that my neck is on the chopping block way too often. My district has very few health related policies and makes most of their decisions without evidenced-based information. As the only healthcare professional in the district, I really feel alone and vulnerable.

Has any one else had these feelings? How did you come to terms with them? Are you still in school nursing?
