Personally I have never had this problem because my T does not work through email or text.

I have given him some of the worst of my worst several times in writing but I hand it to him at the beginning of session. He reads it immediately and responds in depth to everything I wrote. It will usually take the entire session and those have been some of my most productive times in therapy.

Occassionally when I have not had a chance to print it out I will email the Word doc while sitting in the waiting room and ask him to print it out as soon as I get into session.

Only once did I email him with my feelings prior to session and that was after a SI session where I cancelled the next session. He called to check up on me and insisted I email him either way prior to next session. I was experiencing a rupture that he was not aware of. Since he was making me email him, I decided to send the Word doc the day before and explained to him that I wanted to give him a heads up on what was going on in my head and I didn't want to put him on the spot by giving it to him in session. I did not expect a response. He was great the next day. He immediately addressed my concerns, apologized sincerely for his actions and told me how he planned on changing for the future.

In short, I always find it more productive and successful to let my T respond in session. Emails and texts are finite conversations. There is no connection or nuance. No opportunity for immediate feedback and for conversation and clarification. Yes, sitting with your feelings for a few days is sometimes difficult and painful but I find the results are well worth it. Besides, my T always says every time I sit with my negative feelings mindfully I get a bit stronger and more able to tolerate my emotions which afterall is one of the goals of therapy.
