Budget after a layoff: what did you cut first? (update)

I have 6 months of savings and I am trying to stretch them after being let go as a dental hygienist. I worked as a dental hygienist before this. I am nervous about the credit card minimums. What helped the most?

Keep everything in writing and save the confirmation numbers. It saved me later.

A simple budget with three columns, fixed, flexible and optional, made decisions faster.
