Oh, that's exactly where I think, and think, and think in spirals. I suppose I am at my 10 hours of phone screentime per day just not to fall in this dark thoughts spiral.
When we think of 'puzzles' in the most concrete way we think of problems that are challenging but ultimately designed to be solved in a satisfactory way.
But many problems that we want to solve aren't necessarily fair to the problem solver. They can have multiple possible solutions, only half solutions or no feasible solution at all. Some of the solutions could be obvious, some of them hidden to a degree that you may never find them. And when you find something that could perhaps be construed as a solution there's no guarantee that the solution tells you it's a good solution - or if there are better solutions hiding behind the next hill. And some problems will seem very easy to some other person but insurmountable to you. And you might never even get a satisfactory explanation to why that is.
For those problems we need to either learn to accept that the solution process never really ends and/or learn to accept and settle for a fundamentally unsatisfactory partial solution. You might one day wake up and feel that the problem is actually solved or doesn't bother you that much anymore but there's no reason to bet on that. Better to bet on acceptance. That way the process and the problem can possibly settle in our mind regardless of outcome.
Such acceptance is not easy. It can only come with practice, and by also accepting that punishing oneself for being human does not make anyone happier.
