If that's how you feel then it seems fine. I'm not a T but I think that if after 9 years you feel you don't need to go to therapy any more, then you will know best, and the therapist should accept this and support you in this. Unless there is a really specific situation like you have been hospitalised against your will or something. Was it for a specific reason when you went to therapy in the first place, and do you feel you have finished with whatever it was?
If so then I think you should leave if you want to.
