Cover art for Climbing the Walls lyrics by They Might Be Giants

Pacing the floor, grinding your teeth, going nowhere, stuck in a rut…

So you make a change, any change. And now you're climbing the walls, driving yourself crazy, stuck in another rut.

Going from one dead end to another, never making any progress.

(I like the Metamorphosis interpretation a lot, but I also wanted to add my own thoughts.)
