Obsession

Friday evening 10 pm and all I think about is getting though the weekend and getting into next wekk. What is wrong with me?? I have a party planned for tomorrow night and expect somewhere between 20 and 30 guests, I have baked snack foods and have my liquor store list and grocery list ready to go for tomorrow morning. A little decorating in the afternoon and I should be set for the event. But in the back of my mind, all I can think about are work related items--research projects in developement mode, writing up data that I already have, and teaching my class. Why am I suddenly obsessed? Where did this burst of work related energy come from? How do I turn my brain off?
