Preparation Anxiety

I'm going to begin my blog before I'm actually in Spain. I know, kinda silly. But I might as well blog about the whole experience not just the time there. So the time before begins about now seeing as I'm beginning to get anxious about the preparation surrounding the whole trip.
Honestly, I haven't really thought about what I need to do. I feel like I have to get past these last few weeks at home before I can devote a lot of energy to what will be required this coming semester. It's like the most exciting time of my summer is coming in these next two weeks. I haven't done anything almost until NOW. Should I take my entire wardrobe? How much money should I save? do I need to get more contacts? Is My Spanish really sufficient to get into the classes I need?

Like I said, anxiety is building.
