My T insisted I talk to her in therapy sessions only. I could and did mail her (to her office) a great deal; cards, letters, journals, over many years. It was helpful to me in feel connected to her (usually I wrote when she was away on vacation when I could imagine her coming back and reading what I read before seeing me, "catching up") or like she might have more information to work with me during sessions. She did not allow me to bring in other people's thoughts (books) or discuss anything in session I did not bring up.

Eventually, I decided to quit writing her and only talked to her during session, every session and that was it.
