Like Willowleaf, I can imagine it being helpful for learning to reach out to someone when in distress, and seeing that they can react positively or helpfully,and that they will not reject you for being too needy, emotional, crazy, or what have you. Do you find it difficult to contact others for support? Or maybe your T wants to talk to you right when you are experiencing difficult emotions as opposed to processing the difficult times after the fact. I do think that this could also help with healing.

On the flip side, at least for me, there would be so much angst involved with texting. I'd be obsessing over saying just the right thing, over how long it took my T to respond, over the exact wording of what my T said, over when to end the conversation, over how much to say and how much to leave for the next session, etc. I don't think I could emotionally handle the texting, so I guess it's probably important to think about whether you could.
