Exhaustion?

Two weeks ago, today, I went to the Fall Ball at Just Scrap It. The fall ball is an amazing time set aside to scrapbook and be creative for roughly 30 hours. I had a great time, and I got a lot accomplished. Feeling creative for that long was awesome. I came home, did a few creative things, and then I hit a wall like a Mack truck. I find it hard to get enough sleep. I find it hard to think of something to fix for lunches and suppers. I find it hard to operate beyond auto pilot. I'm almost depressed. Could being crafty and creative have taken so much out of me? Did I over do it? Could scrapbooking really have taken me to the brink of exhaustion? I'm not sure, but it is something to ponder.
