Ok, not to duck the hypothetical, assuming you do leave (and to add to the other good advice here)...
We tend to focus on the things we can control, and things we understand; we stay in a context. A job change is a chance not to be stuck in that mode.
The biggest difference in work latitude is the overall need and value flow. It's just easier to be on a big river than a tiny stream, modulo competition. So consider the world in terms on value-flow and competition. E.g., tech value flows can be large but volatile, and competition includes outsourcing and automation on top of new grads. In-person health care services require long credentialing but then are protected by those credentials and the difficulty of automation; but because it's in-person, the value is hard to scale unless you're a rainmaker (i.e., a doctor). And so on.
A job change is also a chance to reset your life. Yes, try exercise and address some other self- and social-debt, but don't load yourself with obligations. The key thing is values, how you feel, and your liveliness relative to life. It'd be a good sign when there's a nice view, and you really feel it, without distraction from your psycho-social-economic context. When you discover your values, you pretty naturally start working on them and work isn't hard.
