This has been explored many times, but I believe therapists often do not reckon with how much their presence in our lives means to us. It's a fatal flaw with therapy sometimes. When someone gets pregnant, they still see their friends, family members, acquaintances , and in other fields still communicate with key clients and work. It is a big blow to absorb the loss of a cultivated attachment suddenly, in a way over which your voice and sayso have no influence. They spend so much time teaching us our voice is the one that matters in the room, and then it is the big reveal oh no actually it doesn't. I'm very, very sorry this is happening, especially that it is more than once. My good friend who is a clinical psychologist fretted about her patients when she had both of her kids, and went back to work earlier than she planned. She is simply happier working. Maybe your T will have a reaction like that? Covid makes it more complex, I guess. So sorry.
