I am excited for this new stage in your life. I know that at the very least, you will gain a better understanding of yourself. One of the wonderful things about getting out of your comfort zone is that it helps to show the things you have been accustomed to and normally don't notice.
I have a personal philosophy of intentionally "sabotaging" myself because I am reluctant to change. Examples of these sabotages include joining a fraternity, moving to the other side of the US for an internship, and now I'm currently living in Austria. It's definitely challenging, but it has helped me to grow.
Remember that freedom comes from within you and is not defined by your external environment. These changes that you experience only help to show you were you need to be freed from.
