I would also suggest talking about this with your new T if you haven't already. I switched Ts when I moved a couple of months ago and it was really hard. I still had (and have) strong feelings about my old T. But it made it better to talk with my new T about it. I thought she wouldn't want to hear about how connected I felt with my old T and how much I missed her. However, it was the exact opposite. She was happy to hear about my relationship with my old T and how it worked and how I felt. I was feeling I was betraying my old T to connect with my new T. But I found that it helped to talk about it and made me realize that I could feel attached to both of them without betraying either of them.

I know this did not directly address your concern about your connection to your old T, but I hope it helps you.
