What happened to my muse???

[trinsy]

I'm seriously frustrated right now.  I cannot write.  I seriously can not write!  I have two chapters left of Canis Majoris, and I know exactly what's supposed to happen in them, and yet somehow I cannot write them.  Oh, I try.  I try and I try.  But it doesn't happen.  Either I don't write anything at all, or I don't write what's supposed to happen, or I write something truly horrible, or (most commonly) a mix of the three.

And, quite frankly, it's getting really annoying.
