It's not your imagination!
There's a real reason for this and no, you are NOT crazy.
This is one of the best blog posts I've ever read about this. Every pastor and pastor's wife need to be aware of this great writing from Clayton King about what happens inside a pastor's body!
Incidentally, I was feeling like this today as I usually do on Mondays. Even though I took a four hour nap after choir rehearsal yesterday I still got up today and felt like I had been beaten to a pulp and it was so hard to get going. I was reminded of this article and want to share it.
Clayton King is also a great blogger to follow and you can do so by going here.
