Explaining a gap after caregiving or layoff - what worked for you?

I have been out of work for 9 months and worry about the gap. I have been trying to stay organised about it. I have done some volunteering and a course during that time. How did you handle it on your résumé?

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