How do I handle a long gap on my résumé? after 4 years as a pharmacy technician

My résumé shows a gap from a layoff and some health issues. I am nervous about being filtered out. What do you say in interviews?

A short, honest line such as 'family caregiving' is enough for most employers. They mostly want to know you are ready now.

Thanks for writing this out. I went through something close to it 8 months ago, and it settled down once I kept a simple log of every call and form.
