My first T when I was really young terminated me because her supervisor said she had to. I didn't really understand it, and I didn't really get it, but I don't remember being particularly traumatized by the ending or whatever. I just accepted it.
Former T and I had to stop because she got MS. It wasn't sudden/sudden, it was surprising, and it took a bit of a process but I didn't want to stop seeing her, I just had to stop seeing her. I'm still getting over it. I cry a lot, that's how I deal with it. Kit
