Here's something to cheer you up. No matter what's going on in your life, you can look at this photo and smack yourself in the forehead and say, "Oh, geez, at least I'm not painting closets!"
Painting actual rooms is like bathing a dog. Not a lot of fun all the time, but parts of it can be entertaining, and if all goes well, it can be kind of Zen-like.
Painting closets, on the other hand, is like bathing a cat. It's messy, it's frustrating, and no one has any fun at all.
