Hibernation

That's basically what I've been doing, now that I think about it.  It started off with being tired:  going to bed at 8 pm.  Then 7:30 pm.  Then 7 pm.  I'd sleep all night, at least until Sarah got up at 4:30 for a feeding.  I was still happy and peppy, excited about planning next year's homeschool curriculum, and thinking of things for us to do this summer.
