That bulb needs replacing. Those socks have a hole in them. The door has a weird splat on it where you spilled your coffee against it. The bathtub needs cleaning. There are so many bits of random crap around the house that you don’t even know where to begin. ARGH!
Everyone gets to this state of overwhelm at some point, mainly because those little shitty jobs seem so unimportant. They lend themselves to the “I’ll do it later” mindset because they don’t have an immediate effect on what you’re doing. Or do they? Add up all the tiny moments of irritation each one causes, and all of a sudden, you have a whole bunch of crap to deal with. Throw out the socks. Make a list of odd jobs and do one thing a day. You will feel better, I promise.
