What my T said was any handed note to her counts as a therapy note and is shredded the day it needs to be but any email has to go into my file. She even asked if I want them in my file once. T at the beginning asked if I wanted them back but I explained as soon as she is given it it's hers. So now she only askes if I'm particularly nervous. I would say your therapist wanted to examine the note more to help you. My T has told me she'll never use it against me because I need someone (professional) in my corner fighting for me if things go bad and I can. I would ask your T how she chooses what goes into your file.
