Maybe you know this one:
I am twitchy to be working, but I am at a complete loss for a solid image. Vague ideas, only. Picking up and putting down sketchbooks, art books, writing books, picture books.... scanning websites.... looking through all my photos.... no no no. That's not it. Roaming about the house rearranging plants, pillows, dishes. Tried to go out for a walk today for a little change of scenery and inspiration. Too cold, too windy, too... icky. Tried to respond to questions for an online interview. Words are flat, too. The irony? One of the questions is about dealing with creative slumps.
