I've had off sessions before....some really awkward, and it's always hard to believe that it's not your fault. But, the reality is, Ts do have bad days....I wonder if you can tell T that you noticed she was distracted?

When I've had the courage to bring it up with my old T, I was usually validated that she was indeed having an off day.

Either way, I hope she calls you soon so that you're not stuck in limbo for long...
