People are acting as though we're going back to a pre-industrial economy with this. It's not true. The power isn't going out. The water will continue to come out of the tap.
So my suggestion short term is: learn to cook if you don't know how to. Not fancy, haute cuisine, but how to take whatever's in the pantry and make something tasty out of it. Learn how to grow some produce in small spaces, even if it's just herbs.
Learn how to not spend money. How to reduce your energy and water usage. How to do basic repairs and projects yourself. What you have to buy in a time of logistical disruption is time. If you can increase the time you can be without income from a month to four months or from six months to two years, that is a remarkable difference in your resilience.
