Not OP, but similar situation, I got fired back in november of last year and had to cash out my 401k to survive. Had to pay off a lot of debt, and now I have like 6k left in the bank and it's dwindling quite fast with bills and such. I try to stay positive about it and apply to jobs every day on multiple job boards- but a lot of other people are having the same issue. Some people going for over a year without even a single interview. Mostly jobs like IT and Remote stuff that is just completely over-saturated right now and mix in the fake-job postings, internal-hiring shenanigans and all the AI bullshit. It's not looking good. I'm learning how to weld and going to try to go around fixing equipment or something on the side to keep things rolling until I can land a job. It sucks, but you have to keep moving forward. Can't pull yourself up by the bootstraps, because there aren't any boots to begin with.

Also, OP, If you have the option of temporarily moving in with family, just do that. There is no shame in resetting things and starting over. You're still young, and try to think more positively about your situation- it's probably unlikely that you'll end up homeless if you keep applying to jobs and just generally trying.
