I'm retired, but I still have income. I know how fortunate that makes me. I've been in financial straights before in my life, & the worry of how you're going to pay your rent or how your going to buy a few groceries, even, it never leaves you. It's always there, even just a tiny bit, like you said, when you go out for a walk, the worry never completely turns off. It drains you. When I was a young girl, an older woman in our community accidently left her car door open in her garage. She didn't drive very often & the next time she went to start the car, the battery was dead. I remember the men in my family laughing as they speculated how long it must have taken for a little dome light to drain a car battery. That's kind of how this is. Even on days when you have it under control, it's still there, just like that dome light.
My nagging worry is a different health issue that I've done nothing about for a year due to the virus. There are going to be a ton of folks who, when this is under control, are going to find out how much worse of condition they are in because of delayed medical care because of Covid. The impact of this pandemic is going to last for decades. 
I wish I had some comforting words for you, other than "this too shall pass." Positive vibes & a virtual hug.
