Talk to me about culture shock and moving to a new place.

I've been in San Jose for two weeks as of yesterday, although it kind of feels like two months instead. I think I'm adjusting okay, but from time to time I have fleeting moments of wondering what I'm doing here and if I made the right choice. I think it would be different if I had visited the Bay Area before I moved, but I had never even to California before two weeks ago. So, tell me your stories about moving to a wildly different place and how you got used to it.
