Well, I moved from my old house. I left most of my friends. It was very sad. Epsicially on the car ride to my new house. I cried. But what you should do is make new friends. You might still have her number. I have all I of my friend's numbers. I still call them all the time.
It is sad, I know how you feel. You can still have visits with your friend and look on the bright side, visiting when she is far away would be more fun. Rare things are always fun (Expect for sicknesses) Every time you see her, you'll be more happy then you were when you were with her.
