I would try to find something in the future, something about your new place perhaps, to talk about so you can get a little bit of a sense of continuing and your T having been there with you when you get there. Maybe discuss if the new T should/is going to call this T to talk with her or how hard it might be to work on your issues with being preoccupied with moving, etc. Have you done any of the searching for a T in the new area yet? I'd try to maybe write a poem about what you want in a T (kind of like in Mary Poppins) and have it be obviously about your old T too so you can remember what you are looking for in a T and also recap what you have been able to do (actual activities you have done since seeing T that have been healthy for you) and you'd have that to give your old T and take into the future and to your new T and with yourself. Kind of a "notes from my past self" of what you'd like to remember in the future.
