Have you considered having your own business? You sound like a capable person who would do well being an independent worker.

I came to feel all of the above about my profession over time---now, I work in a position and place that is positive, where I am the only nurse, working with kids and teachers---camp---no politics, no competition, no drama bigger than homesickness---and the satisfaction of being able to help others, and participate in the activities that interest me.
