Awww, I'm sorry to hear that your good friend moved away! I know how that feels. I have a good friend who is like a sister to me, and years ago, she moved from Ohio to Arizona. It was like a wrench, and I cried like a baby for a while. Whenever I was going through something, she was right there for me. On hindsight, I used her as a spiritual crutch, and after she left, I had to learn to walk spiritually on my own, in order to mature. I do miss her presence here, though, even though she's just a phone call away! Occasionally, she comes back to visit with family, and we try to get together at those times.
I do hope that you'll adjust in time, and that there will be opportunities for you to be reunited periodically! Meanwhile, stay in contact with her by other means. (Phone, internet, Skype!)
