You could say that you did home-health.
These days you don't have to have a license to be a caregiver and alot of people work on their own instead of through an agency.
They always have ads on craigslist for "domestic help" for home health/caregiver jobs.
You could say that you just want to break away from health care.
Get two or three people for references. Honestly, you are a caregiver now, just in a different way.
Most caregiver jobs entail: helping with a bath/shower, dressing, grooming, light house keeping and cooking a meal or two.
They mostly want a companion to talk to and company, after you do the above, that is all they want.
It is low pay though, around $10/hr if you're lucky.
If you could get someone to vouch that you have been a great caregiver it would be easy to fudge the resume a little.
