Hmm

Okay, it seems like it's something that niether you or your T expected to happen. If you feel like you got along with her, don't hold back on giving her a ring. I am sure that if you two have a close-ish relationship, she will understand that some of her clients will find out where she is to continue their sessions with her. She would also, understand that it isn't easy when something like your situation happens so suddenly. And that changing to a new T, isn't that easy.
She probably could not suggest to you that you come back to be under her again, you would have to ask her out right. What A. told me is, "if you don't ask, I can't tell you!" It isn't weird or creepy. It isn't stalking. All it is, is a client who wants to continue their therapy with the same person. It is within' her rights to deny you, but if you two get along okay, then she shouldn't. But do prepare yourself for the possibility of her saying no.
Call her, ask her and find out if you can continue to see her. If you don't, you will never know.
