Don’t overthink! I experienced same stress before during pandemic since my job becomes temporarily close while I have a lot of fixed bills on monthly basis that need to be paid especially insurance.
I focus on my current resources and try sellings goods on social media which helps me a lot to get extra income. I live near the manufacturing area of goods which I resell it on lower price compared to retail. I will not overcome this stress if I will just overthink about the problem and stop finding solutions. Check what resources you have and capitalize on that to get extra profit that will cover your expenses.
I did the same thing as you selling online when my job or my office was closed. I had bills to pay every month even though I had no income at that time. The more I thought, the more stressed I became, so sometimes I didn't think too much about things. This is because we have to accept that when we are not well, I did what I could do, such as buying and selling online and in the end everything was fine until my financial condition improved over time.
During the pandemic, this is one of the reasons why many people have problems that make their financial pressure even worse. Even many people who have businesses felt financially fine before the pandemic. But post-pandemic, money continues to be a pressure that makes them stressed. We have a lot to learn from this pandemic, even though financial pressure has now returned to normal, we must not neglect to use the pandemic several years ago as a lesson so that we are better prepared to face the same situation, perhaps not another pandemic disaster, but a global economic crisis.
what you did was right. While you have the opportunity, make the best use of your time to continue looking for additional income. Apart from that, managing your finances well, and having a money post will teach you how to be aware of all your financial decisions. Stop for a moment to celebrate something that is not important, use money for investment because this is one way to overcome financial stress in the future.
