Trimming expenses while I search - any advice?

My income dropped to unemployment benefits and my bills have not changed. This is my first time dealing with any of this. I listed every subscription and found several I forgot. What helped the most?

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

Thanks for writing this out. I went through something close to it 5 months ago, and it settled down once I kept a simple log of every call and form.
