That's the alarm system telling you to wake up and start looking around for a change. For whatever reason, we seem to have a meta-cognitive system that watches for stagnation and creates unease when it is detected. Am convinced that you can't disable it entirely, but you can self-mediate or ignore it. Either route is not great, as you're aware on some level that you're refusing your destiny (of sorts).

I think about this quote a lot:

"i keep re-encountering with a shock the way that most people do not know, at all, that the problem the entire universe is devoted to, that it crashes us into walls, throws us off cliffs, tortures and murders us to try to solve, is that of escaping local maxima"

Thus, I'd implore you to stick with the feeling and use it as impetus to change for something new.
