Oh geez, I'm sorry, that really sucks. I know that "stuff happens", but you'd think people in the therapy-profession would be a bit more aware and careful about such sudden changes.
I'm so sorry Ad Intra.
Are they setting you up with someone else at the agency? Is your T going to be doing any sort of "transfer" of your information? Or are you having to go start looking for Ts from scratch?
Good luck... and again, I'm sorry! I'd be incredibly shocked too, and probably react exactly the same way you did. It takes a bit for things to sink in sometimes!
