In the (long) time that I have been seeing her, my T has had 3 different offices, before Covid. In addition, in the office she was in the longest, she changed the furniture around and/or bought new furniture a few times. Now we are "seeing" each other online, she in her home office, me in my dining room "office." Of course I would rather be seeing her in her actual office, but getting to see her home office has some advantages. I can see that her paperwork is as messy as mine, and that is a comfort. I know that, someplace in her house, is a poem I wrote, had framed, and gave to her; the other one is in her work office. I also know that my book is someplace in her house. So a part of me is in her home with her, and that's also a comfort.
That said, I understand, Merope, the difficulties involved for you each time your T changes offices. Try to create a new ritual for the "online" space, one that makes you feel calm and safe. If you pray, say a prayer. Have a cup of coffee or some other drink that you like. Do something just for yourself. Good luck.
