Pre-occupied

I am consumed with this. I have a hard time doing much of anything, without thinking about the upcoming procedure. I can't run. I can't work. I don't do much with my kids. It sucks. I'm not all that depressed, just pre-occupied. We'll call it that. One of my previous thoughts was to wait until after the holidays, so I could enjoy them with the family and then start new. Now I can't imagine waiting any longer. It's not like an "I can't wait" for something good, but I can't wait nonetheless.
