This. I have to say my happiest and most productive period was when I didn't have a desk job. I found a trick that worked really well was to start the day with a list of accomplishments that I thought would take less than 6-8hours. Often framing it like "I'll be happy if I do X,Y, and Z". If I finished in 15 minutes, I was done for the day. If I didn't finish by my 6-8 hour time limit, then I was still done for the day, and tomorrow I'd try to break up the task in such a way as I could finish parts of it in less than a day. I think an important part, and something OP might note, is that framing the tasks in terms of "happy if" really changes the psychology of the process. No longer can you say "I did all this stuff and it's not enough", since you already identified enough at the beginning. This coupled with the constant readjusting of expectations really helps avoid feelings of anxiety. I'm not sure this helps for a failing business (or if rent is due tomorrow) but it certainly helps if you have even a month's runway.
