Explaining a gap after caregiving or layoff (Omaha)

My résumé shows a gap from a layoff and some health issues. I have done some volunteering and a course during that time. What do you say in interviews?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

Keep your skills fresh and mention anything recent. It shows momentum.
