Wie amerikanisch bin ich? Questions...

So this has been a tough sort of time for me, intellectually speaking that is. I have given a lot of thought and energy to discussions about my experiences thus far, but I am having real trouble articulating this to everyone back home. Part of me is ready to come home and see all the things I've missed, but another equally valid and entrenched part of me would love nothing more than to stay here in Germany and continue my studies and explorations.

My questions for the readers out there: How do I reconcile the two of these ideas? Is there some sort of middle ground, particularly when there is no geographic middle ground? Another thing I have been ruminating on is the idea of a "reverse culture shock", an idea my roommate and close associates have discussed. Can I successfully reintegrate into an academic milieu so much more defined and regimented than Germany? Will I be able to sort of assume the "Berkeley Will" outfit that I left behind?

As my time here in Germany draws to a close, I am faced with ever more questions, and me being me (I love knowing the answer), have encountered frustration in that there seems to be no satisfying answer. On another note, I turned 22 this last weekend, and I feel loads smarter and more worldly. :D
