Making savings last after losing my job, software tester here

I have 4 months of savings and I am trying to stretch them after being let go as a software tester. I worked as a software tester before this. I listed every subscription and found several I forgot. What did you cut first?

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

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
