Most of my entire therapy was done by writing letters to my T in between sessions. I wrote about all about my feelings brought up by the previous session. He would read them silently to himself during my sessions and comment on what he thought was pertinent. At first I even made him go outside of the room. I would have been horrified if he'd ever read them out loud. These letters would take me hours and hours to write. It was very helpful. I have verbal/receptive issues so this was the best I could do. It was a place to start and I think that could be good for you to. So you started with the phone conversation and you can move forward from that during your session.
