I feel you, like my name indicated, I recently learned how to do knitting and crochet.
I've never tried these techniques before, and in last 5 days, I made 3 balls for my cats and finishing scarf right now.
For me, this waiting-without-deadlines anxiety is sometimes so overwhelming that I am having trouble focusing one my present stuffs - research projects..
Maybe changing hobbies like me maybe work?
but then again, this kind of pain is just unavoidable....
