the empty feeling you feel when you realize that as of July 2011, there will be no new installments of Harry Potter, and that the Deathly Hallows is going to make you cry because it will all be over.
Person 1: "Man, I can't believe how good Deathly Hallows was."

Person 2: "Yeah, this just means I'm gonna have a bad case of Harry Potter separation anxiety now that it's over."
