How do I explain a layoff in interviews? (update)

They always ask why I left, and I freeze. I worked as a dental hygienist before this. I do not want to blame the company. Do they ask follow-ups?

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

Say it plainly and move on to what you can do. Interviewers usually move on if you do.
