If you're crazy, then I'll be in good company.
I feel EXACTLY the same way about my daughter if I don't hear from her within a couple of days. But then she and I have had a rocky reunion. It could be that you guys are starting to "settle in" to your life relationship. I'm so happy that things have gone so well for you two.
Maybe send her an e-mail greeting card or forward a funny e-mail to her--no message, but letting her know you're thinking of her. Keeping things light are always better...
In the meantime, rent a movie (or 10) to distract you.
Hope you hear from her soon!
