You guys are wonderful! You're right, I was just feeling crushed for a little while. I'm back and bouncy now!
Actually, turns out the rejection was just the kick in the pants I needed. My WIP wasn't going the way I wanted it to, I wasn't falling in love with it, but I didn't really want to admit it. Stewing about the rejection all day yesterday helped me figure out what I wanted to do. I started running through the mental file of ideas I've been meaning to get to but haven't found a place for yet, and things gradually shifted into place.
It means a whole new direction for the book, but it has that sparkly feeling! You know, when you have no idea where the story is going but you just can't wait to find out. Where you fall asleep thinking about it, and you hop out of bed in the morning ready to get to work. Between pieces I've salvaged from the old version and new things I've done, I'm already at 3K, and I haven't even eaten breakfast yet! (oh, wait, that might be why my tummy's grumbling...)
So, life is good again. I'm going to send out some more queries today for Agatha, and go to the fabric store and get stuff to make a new skirt because I've lost enough weight that nothing I own fits anymore, and by bedtime tonight I'm going to try to reach 5K.
Thanks for all the cheering me on, guys!
