In which case the best thing to do is to just take a break. It'll come back to you in time once it's off your mind for a bit. If you want to speed up the process just do gestures or something else instead of trying to pull something from your head. Not everything needs to be presentable.
Oh and change up your tools or try a different program entirely.
