It's very understandable to me, as I respond strongly to spaces. I think it's a really good idea to have her walk you through the new space if possible. And certainly to talk about how you're feeling with this before and after moving. There's a lot of attachment feelings of safety and security connected to the space, and it's natural to feel a concern about losing that; it awakens other losses.

My T moved offices 4 times during the years I saw him and it was always a struggle for me, even though he kept the same furniture, etc, and replicated the arrangements as closely as possible. I usually responded by being pretty hyper-vigilant for awhile. But working through it also led to some really good progress, too.
