no thoughts head empty

For the last one/one and a half month I had been able to write a little (~250w) every day, which I had not been able to do for... years at this point. But as of the last couple of days, I once again can't -- I don't even have any ideas for what to write and all my old ideas are faded like ashes. It's as if whatever animating force[1] made me able to Do Art is... gone. I can't even daydream anymore! WTF

If anyone has any idea what's going on and/or how to fix it, please tell me. I'm kind of freaking out over here.
