Whether or not you’re excited to return home from living overseas has no effect on how you behave when you finally arrive in your home country. You'll probably feel a bit lost, a bit of reverse culture shock and most likely sadness and emptiness as you start missing the comforts of studying abroad. Even if you were homesick overseas and were excited to return home, it will take some time and effort until you feel comfortable in your own home again. As odd as it sounds, don't forget you're taking a new person to an old position that's going to take some readjustment.
