7 months is not all that long especially when you are starting with someone new after 12 years. My Pdoc and I have been working together 8 years. She is comfortable and familiar. There is so much I don’t have to say because she already knows. Sometimes she feels more like my older sister than a doctor. Things are easy and effortless. But it wasn’t like that back at the very beginning. I liked her and all but there wasn’t what there is now. My current T is amaizing, I feel so lucky getting to work with him. From the very first session being with him was like being with my closest mentor from college. We have been working together just over a year. There is so much we are still figuring out, so much background he still doesn’t know.
It sounds like you had a really great relationship with your first T and I am glad it worked so well, good T’s are hard to find. It doesn’t sound like this new T is doing anything wrong but that she is just not as comfortable as first T. Give it time, you are still grieving. Relationships take time. Maybe it will take some time to catch new T up on everything, maybe you will discover she doesn’t need to know the same everything that old T knew. She will never replace first T but I doubt you would want her to. In time she should become her own kind of comfortable. If she doesn’t or there are other things that don’t fit your needs maybe she isn’t the right T. But seven months isn’t very long after twelve years.
