exhausted

I'm exhausted. When I do nothing, I'm exhausted. When I get lots of sleep, I'm exhausted. And today I found out that this will be my life for the next 7 months. Driving home Monday, I had the ac below freezing and the radio blaring, and still I had to focus to stay awake. This is bordering unmanageable. Pain is manageable, swelling is manageable, emotions are tough but manageable. This whole exhaustion is getting the best of me.
