I can't believe this has been here an hour and more and no one has replied to support you.

I'm so sorry you can't get in touch with your T. It doesn't seem logical does it, that "they" train you to rely upon them to make good therapy (I mean, this makes good therapy, good therapeutic relationships) and then when they aren't there, you're supposed to be ok alone!

What is your plan B? Did T make one with you yet?
I would surely tell him how you felt during this!

Breathe. Talk.
