Why am I so anxious?

For some reason I can't get my head in the game. I'm just anxious and excited and can't focus. I'm so super ready that I feel like I should start counting down days. The only benefit of this spastic energy is I'm working out more so I guess that's a good thing. Is it bad that I've already bought my hospital robe, slippers, going home dress, and flip flops? I'm all shopped out so now what??
