First, was the layoff WARN compliant? The tldr is if 500 or 33% (whichever is less) people were laid off then you were required to receive either a payout of at least 60 day's wages or a 60 day notice. Second, assuming you weren't completely fucked by your company with that barebones requirement, what is the separation package? That is a major factor in how I would proceed.

If the package is substantial enough to live on for a while, try to slim up your budget a bit overall and treat yourself a little in the moment before looking for work. Keep a consistent schedule, and pick up some interests and active hobbies. Set aside at least 2 hours per day for submitting applications, and at least another hour per day on other tasks related to job searching.

Don't let this time be miserable though. Make sure to find ways to relax, get outside, volunteer to a cause, get involved with community organizing, work on a personal project, whatever you feel is worth your extra time. There are a lot of ways to enjoy yourself without a lot of money, like going to your community library.
