You need to express these feelings to her, the ball is in her court, this is all her, its for her to deal with, she needs to balance out these compassionate feelings and feelings of sadness and helplessness for you and not let those get in the way of the therapeutic frame. Its very thoughtful and kind that she cares for you in that special way, and you are a special client to her, your prognosis is very concerning to her. She seems to have let those feelings get in the way of the therapeutic work.

Not intentionally, but its affecting you, I dont know alot about countertransference but maybe this is what this is, and I dont know if telling her you need her not to treat you like a pink cotton ball and to challenge you will help, I hope it does, but you cant change how people feel about you.

Your t, maybe knew these feelings were developing between you and her, and maybe she should have contacted supervision to deal with them I dont know, its so difficult, because, just by our conversations, you are a lovely person, you have a lot to offer, and I can see where your therapist likes and cares for you.

At this point, you and her should compomise and ask her to challenge you more, not to see you as helpless, but its ok to ask you how you are doing through the session, that is common, my t asks me all the time.
