I hate the anxiety of not knowing whether you'll be able to like and work with a new therapist. When is she leaving? Do you have enough time to talk about this sort of stuff with her?
I think you should give the new person a chance. Yeah, they'll be different, but it may not be so bad. I switched between 1...2...3...4... or five T's in three years and it sucked.
