Lost, IMO no T can fix a client. A T can only help a client see the issues and help them see changes that are needed. Its up to a client to do the hard work. Your T has always sounded great. His motive for changing things is not because he thinks your are unfixable... it is most likely because he thinks you are ready for the next level... Perhaps he wants you to learn how to have more positive self talk... to work on seeing a positive in the situation... to see an event from another point of view..
It is hard work to change the way we view things...

Try to trust the relationship you have...tell him how you feel...
