Im so sorry to hear that. Big hugs to you xx I am sort of in the same position at the moment. My main T is still with me, and I honestly think I would die if anything happened to her, or if I had to stop seeing her, but I also started accessing another service. Even though I have only spoken to this other lady maybe 6 times, I felt comfortable with her. During our session last week, basically the first thing that she said was she had spoken to my other T (my main one) and it was decided that I would need long term support, and she just didn't have room in her caseload for me. I shut down immediately. I'm still questioning all the same things as you. I feel rejected...abandoned...too messed up for her to deal with. Im still so very sad. That was supposed to be our last session too, no warning or anything. She said she had set up appointments with the new lady, but because I couldn't make those ones, she has scheduled me in for 2 more with her, then the new lady takes over. I am actually thinking of just stopping. My main T is fantastic, maybe I can cope without needing to see the other one. I don't know...
But I feel your pain :( And I am sorry to hear this
