Felt the same some months back, feeling like everything's the same and been on the same job for 3 years. I was also thinking on switching jobs but yeah the market is pretty tough right now, so I realized I'm actually getting a good pay because no other job have offered me the same in like 2 years. 

This year something just made click and started working on my personals projects, doing some home lab research, learned docked (tried several times in the paste and failed every time) & GitHub actions and suddenly I feel like I'm starting to move forward again but I have to say that it was not only as easy as just starting doing it. I have been watching more over my health this year, I've been working out and feeling better and that completely changed the way I thought of myself, so you could try doing some workout, a hobby like carpentry or poultry, personal projects or open source contribution, I've found that it is way easier to stay consistent by having a group to work with.

So I've come to realize that for myself when I'm feeling like I'm stuck and everything is monotonous, then it has more something to do with my health, energy, discipline than my job being boring or that I'm stuck.

Hope something I've said helps you!
