Making savings last after losing my job after 8 years as an office manager

I have 3 months of savings and I am trying to stretch them after being let go as an office manager. I worked as an office manager before this. I listed every subscription and found several I forgot. What helped the most?

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

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