Making savings last after losing my job - what worked for you?

We are a household of 18 and need to cut costs quickly. Any experience at all would help. I am nervous about the credit card minimums. Did any lender work with you?

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

Subscriptions first, then the phone plan. I saved about $800 a year just by switching to a cheaper plan.
