Do it man.. It was the best thing that ever happened to me!
I can hook you up with a bunch of advice if you need any. Yea you will miss your family and friends, but at the same time you will mature alot during those 6 or 12 months you are away. Plus, you will probably meet people who lives all over the world.
The only thing it requires from you is that you have to be open to change and embrace foreign culture. That can be hard sometimes, but the outcome as previously mentioned is something that you can benefit from in many years to come!
I am from Denmark and I lived in Houston, TX for a year!
