i'm soo with you, i'm actually getting really crabby too!
I sometimes think it's the time of year, so much going on, going from 0 to 60 with the change in temperature. This nice weather sucks the air out of my creativity. Just know you are not alone!
I totally get it.. I think mine is finally coming back.. I hope you find yours soon.. I always love seeing your work..
keep a notebook by your bed. creativity inevitably returns when you are relaxed!
