MikeJ - thanks for the reassurance that it is OK to look around before deciding on a course of action - if the T today hadn't been good I would have preferred to stay with T1, at the moment I don't think I would manage well without any T at all.
MyKidsAreCool - it was so significant today in that T2 asked me if I wanted a glass of water and I had not problem in saying yes - T1 has never been able to get me to accept one in 2.5 years - I have no idea why. Yes an e-mail saying I want to terminate and asking if T wants me to come to a final session sounds a good idea and will set the scene for that session.
Feels a little unsettling in some ways 2.5 years is a long time, but I felt very confident with this new T and hope this will now help me to move forward from this very stuck "groundhog day" type of existence.
