How do I handle a long gap on my résumé? - first time posting

I have been out of work for 9 months and worry about the gap. I worked as a teaching assistant before this. I have done some volunteering and a course during that time. How did you handle it on your résumé?

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

Thanks for writing this out. I went through something close to it 9 months ago, and it got easier once I kept a simple log of every call and form.
