What is my problem?

Why can't I sleep tonight? The temperature is fine, I haven't had any coffee or caffeinated substances (besides a tiny bit of chocolate and a decaf), I've had my warm cup of milk, I'm horribly tired, and yet sleep doesn't come. I don't think I'm jetlagged, since I was going to sleep early when I was in Oregon. Weird...and today at work I was unable to function normally since I was so tired. Maybe I got used to having CC beside me, and now that she's not anymore I can't sleep. My sister told me once that whenever her husband would go away to a different country she couldn't sleep properly for a week or so...

Anyway, I guess I will look for jobs in France for a bit.
