Do You Ever Wake Up Scared?

There are 28 hours left until my thesis defense. My apartment is in various states of transition to Prince Edward Island. Some of my things have been abandoned on the "give away or throw away" shelf in our living room, and there is nothing left in the fridge but condiments. We have resisted dismantling the t.v., not that either of us have time to watch movies anymore. The pets know something big is going down, but their little furry brains haven't figured out what.
How do people live like this? I suppose that people can sustain any kind of madness on a temporary basis. So I keep reminding myself. But alas, I wake up with a jolt, hours before normal, my frantic brain running over a checklist to make sure the world hasn't ended: I'm still in my bed, there's time left to pack, my defense isn't for another 32 hours, and it's all under control.
But is it? How can something like finishing a Masters degree and moving to a new province (likely to stay there alone given the impending long-distance relationship) to start a new job and new life, all over the course of four days... how can anything that full of changes be "under control"? So I wake up scared.
