In non-gif format, The Writer's Raincloud is period of time where you (a writer) feels like:

And that's okay.
Though my mental timeline had me start editing this week, I'm going to push it off until my fervor returns. That's what writing is supposed to be after all: fun! 
Once my self-esteem recharges, I know it will be again
