How do I handle a long gap on my résumé?

I have been out of work for 3 months and worry about the gap. Thank you in advance. I am not sure how much to explain. 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.

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