Sorry to hear that and I’m sure you’ll bounce back quickly.
Let me start by suggesting that if you can, take a week off so you can get in the right headspace for getting ready again to get out there again (if you can afford the time).
Is your resume up to date? If it isn’t, start by refreshing it so that you can start passing it along. If it’s not, use ChatGPT or any other LLM to help with this.
Do you have any friends at other companies or other people in your professional network? They might not be able to get you a job, but if they can cut through the first round of the cycle, that might make things easier.
Are you looking for the same type of job? If you are, are there any other skills/certificates that you can pick up to bolster your background?
Are you open to only staying in the same city or is moving elsewhere on the table? Assuming it’s the right thing to do for you/your family economically, perhaps a job in one city might be easier to acquire than where you are.
The last thing I’d ask you to keep at the top of your head is there is no shame in taking a lower paying job to keep yourself fed/clothed/housed. You know the saying, it’s always easier to look for a job when you have one.
