I don't think it is something they can enforce. But for me I do understand that my T keeps that slot open for me every week and in 20 months has only not been available for 2 sessions (not sure when he takes a holiday). His fee is his wages and in some ways I acknowledge that it is only fair to give notice so that T's are aware of the impact on their monthly salary (not sure how easy it is for them to get clients).

Also I also acknowledge that for me, my feelings can really cloud my judgement. I can get really messy in my head and sometimes it takes me a while to process things and see things more clearly. So for me the other benefit of giving notice is to protect me from jeopardising my progress through acting impulsively and just quitting in response to a triggered feeling.

I also know in my case, I have actually got a little worse since starting to see T - all sorts of old unhelpful coping mechanisms got triggered. I think this is because I have released some of those demons that live in my head, who previously I had managed to lock up. So again for me, I think to just quit now may leave me more vulnerable than before - I would see an extra 4 sessions as being used to make sure I have some other coping strategies in place and also to ensure I have self awareness / insight and knowledge of where I go next.

Somewhere underneath all this, there is also a deep respect for T (although I don't feel at all close to him right now) - and if I put myself in T's place, I wonder how it would be for someone who I had started to know deeply and maybe care about to just walk.

All of this would of course be negated if I knew that my reaction to T was in response to real justification and not just because T had touched some of my buttons.
