Suddenly seeming like a long way home

I set out this afternoon, leaving work early, to make the drive home to Michigan. It's not that far, but it's not that close either - 4 hours, almost exactly. I usually don't mind the drive; it goes by quickly and is usually relatively uneventful. For some resson, this time, I found myself not excited about making the trip. I'm excited to be in Michigan, to see my nephew, my brother. It just seems that as time goes by, I find myself feeling farther and farther away and less and less connected to the place that I'm from. It makes me feel like I don't have a home, because where I live doesn't feel like home either. From where I am sitting, it seems like a long way home.
