How do I deal with moving?

My dad and his fiancee said we might be moving in the next year or so, but I love the house we are in. We've been in the house for about four years. My dad is gonna get a house in my school zone, so no worries about that. It's just I'm not used to so much change. They are getting married in a few months, so I have to put up with a new stepmom AND moving AND going into the eighth grade. Arrgghh! >.< How do I deal with it?
