My therapist said that the termination process can take a long time, it doesn't have to be a case of " ok this week is my last week". It can be a process of months, talking about finishing, being ok with it etc. It's all in my control, i leave when i feel ready. And that by the time i'm ready to leave i won't be in the same place i am right now, it won't be the same loss as it would be to me right now because i will have built up resilience. I won't need her as much or at all by that point. And while it will be a little sad it won't be devastating.
