Thank you all for your replies, I will try journalling my thoughts. I hadn't thought of writing an imaginary email that T would send me but I like that idea.

On another topic, I am thinking of bringing my mother to one of my sessions sometime in the future because she doesn't understand me or this whole therapy process at all and I find it impossible to explain it to her. I'm hoping if she were to come to a session T could help with that. My relationship with my mother has been a frequent topic in therapy and I would like to strengthen that relationship so I don't rely on T so much. Have any of you tried bring a parent to a session?
