Just Little Ole Me Working on My Fourth Book

First, I just have to tell you this. I'd been hearing murmurings around the office about a movie being filmed this morning around the block in P.O. Square with SJP. Yes, Sarah Jessica Parker. And I'd been so antsy in my seat doing work, but finally at 11 I said to myself, I just have to go see if they're still there. So I walked around the corner to DD for a hot chocolate and then took the long way back to the office and walked alongside the filming of SJP's latest movie "I Don't Know How She Does It". First, Christina Hendricks' hair is so red! I wasn't super close because there's a fence and shrubbery, and sadly I didn't bring my phone with which to be a creeper and take pics, but it was awesome seeing them actually filming. Maybe I'll be a small peon in the background if you squint really really hard.

Anyways, on to writing. I have been sick for the past week. I don't remember the last time I was actually sick. I think it might have been two years ago. It came quickly, while I was writing last wednesday night (literally came over me in half an hour) and I tried to ward it off with tea and ecchenacea (however you spell it) but no dice. I still got sick. I had fully intended to spend all of Saturday writing but instead I spent the day in bed watching movies. It was so lame and I felt guilty not writing but I just couldn't muster the energy. So then we get to yesterday when I took a sick day to rest and and really give the mucus a good fight. I slept till almost noon and then spent until 5pm writing. It felt great to really get so much done and I was on this high, looking forward to only a few more days' worth of writing before completion of draft one. And then suddenly a low kicked in.
This seems to happen to me on every book. I start off in the obsessed phase - thinking about the plot and characters and setting every second of every day. It lasts for a while, about three quarters of the way through the writing and I have ridiculous feelings like, "This book is going to be epic!". I often have delusions of grandeur so this is nothing new. But then when I get really close to the end it's like I fall off the happy mountain and suddenly think who the heck is actually going to want to read this - it's the silliest book in the history of books (which is saying something since I've read some really attrocious books). So that's where I am right now. It started after I closed my laptop last night and seems to be permeating in my sickness or something. Maybe when I'm back up to feeling 100% I'll go back to thinking this book is going to be epic, but I wonder, do other authors have the same rollercoaster ride throughout their writing process? Or am I just a total looney?
Anyways, I'm close to being done with the bare bones and then I'll have the two best cheerleaders read it and tell me how awful (or not) it is and that'll set me straight. Until then I'll just keep on truckin.
Happy reading (or writing)!
