Thanks Tree!
I texted her on Friday after the session, and the conversation was :
Suga: I think it's going to be too difficult&confusing for me taper off sessions.I think it would be easier for me to stop,&have an action plan for when it gets rocky
T: Ok. Lets discuss that at your next session with a view to it being your last? Think about it n tell me next week.
Suga: I don't know if I even want to/can come back next week. Seems a prolonged ending to a 'relationship'. Too much effort and emotions
T: I know its difficult but it is important if we do terminate to do it properly and not avoid difficult or painful emotions it triggers.

So, pretty much what you said, lol.
Not too sure how much genuine caring there is, as opposed to just being professional and ethical.
I pretty much have my life together, except -ironically- this 'termination' part
