I doubt all the time that my T cares. I know she does, but something just clicks in my brain and I decide she doesn't. My T knows this (and I think it frustrates her). So she had me do an assignment. I went home and wrote out a list of all the ways my T has shown me that she cares. I wound up with a list of 68 different ways. That has helped me a lot. The doubts still like to creep in, but it's easier to ignore them when I have evidence that says otherwise.
