I think I always thought that the T notes were like a diary as well!!! But to see that does kind of make me feel better, like all my private stuff isn't just out there in my file somewhere...
I think my T does short little notes too, she has a clipboard with one sheet of paper on it, and she doesn't write too often. Works for me, she is very engaged while I am working with her, which is what I want while I am in therapy anyway.
I think I would be more nervous if I knew she was writing a ton while i was talking anyway!
