I disagree:

(1) My CBT was for a set duration after which I was told I would/could receive additional counselling for a period determined by the psychiatrist.
(2) I had a counsellor inform me she had done what she could do, that I had improved to a point she felt she could no longer help me.
(3) I participated in a Bipolar group and was informed I was 'graduating' from the program.

In none of these situations did I have any input or control over. I was simply informed 'it is time'.
