I actually need to clarify this with my therapist on Friday. He doesn't allow between-session contact except for scheduling (though I've snuck in a "Hi I need an emergency session bc xyz happened" line in my email to ask for a session (and he did respond with empathy to the information as in "omg I'm so sorry - I can see you tomorrow at x time" -- but there was zero discussion beyond that))... but, last session, I said something about someone calling a therapist as like a last-resort in an emergency, and he nodded and was like "oh, yeah, when safety was at stake"... so, now I'm not sure if that would be allowed for me if, like, I needed to be hospitalized or what...

My last therapist allowed as much between-session contact as I wanted, and it eventually became us texting every day, multiple times a day. It has led to nothing but PAIN for me... we are now trying to be "friends," and I literally just scraped myself off the floor from a 30-minute melt-down panic attack over him. yet again. And it has been MONTHS since he has been my therapist.

Never again.
I am very glad to not have between-session contact. I feel safer because of the boundary.
