My T doesn't do email.
I guess what I do to try to make it to my next session without contact is... hmm... I'm trying to think of what I do, and all I'm coming up with is a variety of negative coping mechanisms.
I guess I like to listen to audio books and play video games. Sometimes that distracts me for fleeting moments. Sleeping, while not a great coping skill, does pass time that I might otherwise spend distressed.
Personally, journaling just makes things worse for me. I get sucked even more into whatever it is I want to talk to my T about. The fact that I'm writing to nobody feels like a slap in the face and reminds me that I am alone. I have occasionally written things to give my T to read in session, but those are relatively brief since I don't want it to take her forever to read them.
