6-month résumé gap, advice? after 7 years as a bookkeeper

I have been out of work for 6 months and worry about the gap. I worked as a bookkeeper before this. I am nervous about being filtered out. What do you say in interviews?

Thanks for writing this out. I went through something close to it 6 months ago, and it settled down once I kept a simple log of every call and form.

I was hired after a 6-month gap. The manager said the skills test mattered more than the dates.
