I email my therapist quite a bit. Thoughts, pictures, questions. Also, if I'm really struggling with something. She does not always reply, but often does. She will bring up emails I sent at my next session. I've gotten a little discombobulated a couple of times when I have called her office phone and left a message about something I thought about on the way home from a session and she has called me back. I told her I did not expect a call back and she did not have to do that, and she just replied she wanted to.
