Flat on my back

I would laugh if I wasn't actually experiencing it. One week before I am suppose to run the race of my life, one I've been training for months, I hurt my back. How, you might ask? I don't even know. I woke up Friday to some slight back pain and by Friday night I was flat in bed. I was certain it was kidney infection because of the way it came on and because I felt exactly the way I usually did with kidney infections. But no, that would have been too easy. An antibiotic would have fixed that and I would be back to normal today. Instead I am still struggling to get out of bed. Today I defiantly feel much better but after about 30 minutes of light walking and work I need to climb back into bed. Can I tell you how much it sucks??? I guess it hasn't been a total loss, I have read three books. I read Princess Academy by Shannon Hale, Pillage by Obert Skye, The Prophet of Yonwood by Jeanne DuPrau. I also read several runner's world magazines which only made my anger intensify. I am mad. I am really mad. This marathon was going to be hard enough. Then you add in my bum knee. And now, my sore back. I will probably feel better by Saturday. I just think the pain be fresh enough to return. I will cross that finish line. It just might be in a stretcher.
