Yes. You are most definitely not alone there.

Sometimes, it's just a sign that I need/want to get out of the rut & try something different. Other times, it's the depression talking & there seemingly isn't anything I could do to make things different. I can normally recognize when it's predominantly the depression at work, but that doesn't usually make me feel any better at the time. So far, I've always made my way through & eventually either being able to institute some change myself, or on occasion, the hand of fate has come along & done some for me. Either way, I just try to keep trudging on.

It has to be said, that there are also times when I've been stuck in a rut that has been just comfortable enough that I'd probably have stayed there, until some external event has kicked me out.
