It never hurts to talk to a lawyer and see if theres any legal precedent for allowing/requiring continued contact. Or even just try google... never hurts to look.
And, if theres no way for you to see her, I would definetly write her a nice long letter send it via snail mail, explaining how this seperation was not of your choosing, and that if she ever needs someone to talk to you'll be there for her. Then, give her your parents' phone number/address, or someone else who will *always* be able to get a hold of you, so that no matter what happens to her, or you in the coming years, she'll know how to get ahold of you. Good luck!!
