Oh, that kinda sucks D:
I'm not quite sure what to suggest. Maybe a total break from any writing, or even thinking you should be writing, for a while would help? Or perhaps you should just focus on one of your WiPs and see how that goes? Or maybe a focus on a different fandom for a while, or on your novel?

I don't know, really.
I hope you get over your funk soon, though ♥
