You keep trying. You may have to take a lesser job to pay the bills, but you keep trying until you succeed. You also need to understand that the CS market has something of a glut right now and with companies downsizing for various reasons, jobs in CS are tight. When I went through the same thing, I took jobs at small companies, startups, etc., to pay the bills and I kept applying to other companies until I landed a job with one of them. You might also consider talking to consulting firms for contract work, something I've done before.
If you give up, you will certainly fail, so don't give up and realize that the hardships you may experience will make you stronger, more resilient, and better prepared to deal with hardships in the future.
Livecode is the commercial version. It used to have a community edition (free) but that was discontinued in 2021. The various other alternatives (Supercard was clunky and apparently doesn't run on 64-bit systems, PythonCard is dead, Shoes is effectively dead) besides Decker would be something like Delphi (ObjectPascal). There used to be a wxWindows-based system but that seems to have died also.
These days most folks would push you towards HTML / CSS / Javascript and possibly Node.js or Deno. In my mind Hypercard was the bridge between desktop programming and web development. Realistically that's not really bad advice.
For desktop programming, Dart/Flutter (Google recently laid off parts of those teams) are viable as are Python/Kivy (or even Python/Tkinter since Tkinter comes bundled with Python). You might also want to look at the DragonRuby Game Toolkit (Ruby).
Best advice I can offer is know your limits and that requires knowing how and when to say "No". Others have mentioned raising rates, and that works to a degree, but ultimately you have to be able to say "No" when your capacity is maxed out.
If you give up, you will certainly fail, so don't give up and realize that the hardships you may experience will make you stronger, more resilient, and better prepared to deal with hardships in the future.
