Making savings last after losing my job, mechanic here

We are a household of 13 and need to cut costs quickly. It has been weighing on me all week. I listed every subscription and found several I forgot. What helped the most?

Thanks for writing this out. I went through something close to it 13 months ago, and it got easier once I kept a simple log of every call and form.

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