I am trying to clarify the story here. So in 2016 you saw the psychologist (once?) and had a full evaluation done, resulting in some diagnoses.
Then over an eight month period you didn't see or talk to this psychologist, but exchanged some emails with him in which you asked some questions and were given responses that more or less directed you to make an appointment to discuss these questions with the psychotherapist he recommended to you. (Is that correct?)

After eight months of back and forth emails (how many, how often? That may have relevance to the overall story here) you began to see the psychotherapist for CBT therapy. It sounds like you and her were not a great fit. (That happens - most people see a couple of different therapists before they find one that feels like a good fit personality and modality wise). She didn't answer the questions you had, she made comments that didn't sit well with you, and you didn't feel like it was worth it. Is that right?

Can I ask if you were continuing to email the initial psychologist during this time? When was it that the psychologist asked you to stop emailing him, and what prompted him to ask that of you?
I am trying to figure out the story but am not sure if I have it right.
