Budget after a layoff: what did you cut first? - any advice?

We are a household of 11 and need to cut costs quickly. This is my first time dealing with any of this. I am nervous about the credit card minimums. What did you cut first?

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

I called the landlord and the card company early. Both offered a short payment plan, which I did not expect.
