Moving can always be hard on people, i'm sure you'll make new friends in no time. as for losing your best friend there isn't much you can do about that, but remember the good time's with her/him.
You should be able to decide for yourself who you want to live with, if you want to stay where you were maybe you should ask if you can live with your dad? Feel free to message me.
