I agree for the most part, you can't just drop everything because you're frustrated. You probably have people depending on you for income, or find moving basically impossible. I will say this though, you really should keep a keen eye out for something better.
I have a cousin who lives in a rough neighborhood. I don't mean scary looking, I mean bullets flying and blood soaked people walking down the street at night (literally saw that the last time I drove out of there). When I was a kid living there, I always thought to myself there's got to be something better and I hated the area. They choose to embrace it. Now, years later, streets are as dangerous as ever. They're still there and I found something a lot better.
I had a few lucky breaks, but I was watching for them and I didn't let it pass me by. My wife did the same, moved to entirely different countries and learned the language there. We treat our jobs the same, when we find it's something we hate, we work toward fixing that. We talk to management about issues that come up. We job search when we have too. We don't give up, we work toward something better.
As your money scales down, you may have to do a few more things you hate ;)
However I think it might be easier to find joy in things you hate vs just hating them :)
