I feel you! I'm editing and revising, though I've managed to add rather than take away. I pretty much figured everything out, but I've managed to get all tangled up in my query. I've lost almost an entire day of potential revisions to the actual story because I was tearing my hair out with the query. What sucks is that I had a pretty all right query before, but I was forced to change it when my MC's goal changed. This is absolute frustration!!
How is it that writing a 55K fantasy is easier than writing a 250 word letter?
There's no way I'm doing WriteonCon. Oh well. I'll attend if I can (I have to work so I'll surely miss everything), but I won't be posting anything. *sigh*
Hope you can get through all those revisions in just four days. Is there any particular reason why it has to be four?
