Things you should get squared away immediately:
A savings plan
Learn how to Barter
Acquire some skills
If you are in that "good position", hang in there, refresh your knowledge on out-of-band skills you may have not used in a while, or ever used, like foraging, hunting, and butchering, and do what you can to encourage others to follow suite.
If you're here looking desperately for advice on how to survive a rapidly deteriorating economic situation, read the above articles for some basics, then come back. No more income? Check out this one: Cash Flow Types. You're in the VIVE category. Read the linked article to find out what that means.
So, you've done your homework by reading the above and your back and you still have some concerns. Start planning. I like the saying "If you fail to plan you plan to fail." Budget what income you might be able to cobble together, or have remaining, and if you ARE out of work now with no prospects, take full advantage of resources available to you.
Make sure you look at what unemployment benefits may be available to you. Find out if there is food, utility or rent assistance available to you. See if FindHelp.org is something you can make us of. There is zero shame in accepting help in a time like this. Survival is your goal. With a little work, you'll be doing more than surviving, you'll be thriving.
After all of the above has settled into your mind, the next thing you need to wrap your mind around is your own potential. You may have had an hourly job doing something basic. You've worked hard, showed up on time, punched the clock and looked forward to Miller time every day. Your priorities have suddenly shifted. You no longer work for someone else. You now work for yourself and possibly a family. So the good news is: you are the boss. The bad news is: you are now the boss. You are your greatest asset and maybe worst enemy. Don't get discouraged. Take the setbacks and disappointments as they come. I personally think you, and I, should not expect help. If we have an attitude of expectation, or a belief that we are entitled (though we may be if we have been paying into a pension or social security), when we take this mind set, we are putting ourselves at the mercy of others. We fall into a trap of waiting on aid rather than making our own fortune.
So, take stock of your skills. Figure out what all of your assets are. Whatever it was you did before is still useful, they paid you for it, after all. The first and easiest thing to do is find out who else might have need of your existing skills. While you're looking for a replacement job, start considering what else you have going for you and how you might capitalize on it. Maybe you're reliable and can work hard - there are still going to be a lot of jobs out there that don't fit your old job description for which those two skills are prime assets.
Do not fall into the mindset of a job needing to be the ideal occupation. ANY job will do when you have no job. Take whatever hours, whatever pay you can and do that until something better comes along.
The next thing you'll want to wrap your mind around is covered in the articles linked at the top but worth some serious consideration. With the way things are going, presently, you might not have cash, but you have something. Everything has value to someone. If you are able to network, locally, over social media or word of mouth, you have something someone else needs. Look at your surplus items as currency, whether food or clothing or motor oil or tools. Make a trade and make sure you walk away with more value than you gave. It's possible for everyone to come away a winner when trading because instead of trading cash which has a fixed abstract value, you're trading goods which have a subjective intrinsic value. You get what you want, they get what they want and you both "profit". Accept cash if you must, but be aware that cash is going to start losing value if the economy slows enough that price inflation begins to take hold amidst scarcity. It's supply and demand. If workers are unable, for health, supply, or financial reasons, to continue to create product demanded by the market, the product becomes scarce and more valuable as time goes on. If a wave of economic depression continues to push us deeper into a longer recession, inflation could become a harsh reality, stripping away the value of saved cash (so make sure your savings are diversified into durable and trade goods as well as cash).
The sooner you figure out how to make winning trades, the more trading you'll do and the more contacts you'll make and the more successful you'll become at operating less on a cash bases and more on a material goods basis. It has it's drawbacks, namely it's not as portable, but accepting these notions and becoming fluent in them will greatly enhance your situation from simply surviving to thriving. Trading can also allow you to quickly hedge against inflation as you trade in goods valued at market prices, your wealth increases with each trade if done carefully.
Update for 9/2021 - the below paragraph sounds silly, in light of what we know now, to an extent. My views have been adjusted by experience and changes in the body of knowledge we have now, so take this part as a glimpse into the mind of a person trying to figure out how to survive given the information available at the beginning of the "pandemic".
Now, I would be remiss, given the current circumstances, not to caution you to protect yourself and your family. Before engaging in any face to face trading, or even finding another job, acquire what personal protective equipment you can. It is, as of this writing, in short supply, but I expect that to gradually change as the manufacturing sector refits for making PPE and needed medical equipment to fight COVID-19. You can make your own with some skill and ingenuity, but be aware that simple low thread-count cloth, like a loose fitting bandanna, is not going to be any kind of barrier to tiny airborne virus particles. Multiple layers of high thread count, washable, fabric that can tightly fit around your face will be needed to keep you well and from spreading anything you may acquire. Guides are available online, but remember a virus is much smaller than a cell in your body and they can slip through just about anything. Your best defense is distance and good sanitation.
That said, if you're in a bad spot, reread all of the above. I hope you find some inspiration there. I will also say, if you're facing this crisis without faith in a higher power, you're going to have a tougher time of it. Sometimes we need a seemingly irrational faith to look crisis square in the face. I've found a very rational faith in Christ, after much searching, questioning and deliberation. My worries are hence few. I encourage you to investigate the Christian faith. It liberates you like no other, despite what detractors and critics may say or think about it. You won't know until you investigate Christ for yourself. Don't take my word or the word of others - test it for yourself.
