Even though you didn't work in health care you can use that other experience in nursing.
I worked as an aid in a prison. Totally different from being an aid in a hospital and/or other fields. Also, worked as an Administrative Assistant and Bartender for a couple of years.
You can use customer service, time management, working together as a team, etc. to talk yourself up. I especially like fast-learner...
Good luck, you will find something that will suit.
