What do I say about why I left my last job?, recruiter here

They always ask why I left, and I freeze. I also do not want to seem like a risk. Do they ask follow-ups?

Thanks for writing this out. I went through something close to it 2 months ago, and it settled down 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.
