I had a T tell me that he was going to retire in 12-18 months. I was devastated. He had told me numerous times that "we" would work thru dependency issues. In my mind, him retiring was not "us" working thru stuff. It was very destablizing. In T's defense, he told me of the decision as soon as it was made and he fully intended to work with me to help me thru termination and he was sad at the distress it caused. Nonetheless, after 6 months of twice weekly sessions on the topic, we agreed that it was retraumatising me a couple of times a week and that it was not likely to change. So we came up with a plan (not much of a plan-basically that I would bring H to last session for safety and to get me home when I dissociated because we knew that would happen). And I quit the next session. And then it took me a good 6 months of working with other ts to get over it. After about a year, I called him and asked him a couple of questions that were still bothering me.

All that to say, even without being abruptly dumped, t retiring was awful. I feel for OP. For me, it was necessary to stay completely out of contact. Not for legal or complaint reasons, just to help me not feel any crazier. And for me, seeing other ts was important. I was too ashamed of my reaction to process it with anyone IRL.
