You'll get other advice here -- and you'll be amazed at how far down you can pare your expenses when necessary.

I'll offer other kinds of suggestions:

1) I've looked back on my gap periods and realized there were things I could have done to better use my time, but in ways not directly related to finding the next job. You can only "job hunt" so many hours each day, you'll have to do other things too. Finish your degree? Maybe, if it feels productive and not enervating. Get a weird side certification? Might be more energizing to get that welding certification, or something orthogonal, not necessarily career-oriented, but productive and distracting.

2) Get physical, if you aren't already. It's a great time to work out (you have the time), and the application of discipline towards bettering yourself will carry-over to the other things. Wanted to do something that employment blocked before, like the Appalachian trail? Don't not do it because you don't feel deserving. That's one of those black holes you have to work hard to keep at bay.

Bonus:

Apply for unemployment benefits.

Find a way to be of service.

Lighten the load for your wife.
