OP sounds rough. Be strong, whatever goes up can go down, and whatever goes down goes up. Don’t try to compare your situation to others it never helps. You have your own trials to deal with (sorry health I don’t mean to be insulting).
But sometimes the best way is to sit down and come up with a plan on how to fix things. Think about what you CAN do and if something seems impossible… leave it alone… and after you’ve done what you can… the rest is in Hashem’s hands…
