This was my first time being out of the US, I was away for 3 months. I was in eastern europe as well as Italy and Austria. I just got home on wednesday and its a bitter sweet feeling. I'm very glad to be back in my own bed, see my family and back to my usual diet but I'm also a bit depressed. Is this normal? How do you typically feel when you return from a "world trip" whether it be a vacation, study abroad,business,etc?
