7-month résumé gap, advice? - 7 months and counting

I took time out to care for a family member after working as a dental hygienist. I am in Tulsa, in case local advice matters. 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 last year, and it settled down once I kept a simple log of every call and form.
