I've hit it this week.
I started to write couple of things, halfway through them I tossed them, either too corny sounding or not even a hint of melody.
One tune I posted I realized was garbage and I pulled it down.
All the covers I'm learning are stuck in quicksand, too clumsy sounding and I feel like I lost my touch.
This is a bad one, usually its my composing that takes a hit or I'm crashing on my covers. I've never had both go bad on me at once.
