I have no clue....I'm so indecisive!!!

So I found out today that my sisters roommate is moving out next semester and she wants me to move in with her. I don't know if i want to do it though. I love her to death and I know it would be an experience but I don't know if I could be away from home that long. If she lived where I do it would be no problem, or if she lived somewhere cool. I don't know. I have a lot to think about.
