I feel pretty settled here, three years on, but I moved a LOT as a child and didn't have the same connections to home that many people do. That said, on of the things I struggle with, oddly, is being so easily recognized? I am the *only* American a lot of places, which makes it easy for people to figure out who I am/recognize me from a description/remember me, etc. For someone who is naturally fairly introverted, I am frequently made anxious with all of the, for lack of a better word, attention I can get. The teenagers at the barn where I ride all knew my name before I had any idea who they were, colleagues at work tell me they've heard about me, etc. It can be overwhelming, especially for someone like me, who generally guards personal time and energy quite closely.
On the other hand, it's been good for me, in a way. I've been saying "yes" to more social stuff (which DH loves as he is wayyyyy more social than me), and I've learned to not try to fade into the background quite so much. But, yeah, exhausting!
And never mind learning to drive and navigate over here!
