I am sorry you are feeling bad. I just wanted to say I think maybe the different office could have a lot to do with it. I had the same experience when my T moved. It didn't feel safe. I was not happy see changed where she met with people. I was used to the first place, the furniture, where I sat, where she sat, the tree outside the window that I would look at when I was trying not to cry, etc.etc.
I think it takes a while to feel safe in a different place. I am fine with it now but it took me a while. Be gentle with yourself. This is a huge change even though we that are in therapy may be the only ones that understand that.
