How do I handle a long gap on my résumé?

I have been out of work for 14 months and worry about the gap. There are 13 people counting on me, so I am trying to be careful. I have done some volunteering and a course during that time. What do you say in interviews?

Thanks for writing this out. I went through something close to it 14 months ago, and it settled down once I kept a simple log of every call and form.
