How do I handle a long gap on my résumé? - 3 months and counting

My résumé shows a gap from a layoff and some health issues. It has been weighing on me all week. I have done some volunteering and a course during that time.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

I was hired after a 3-month gap. The manager said the skills test mattered more than the dates.
