My heart breaks for you, stringcheese
it hits close to home because I had a similar experience with my T a couple sessions ago where I had a flashback response and was absolutely terrified that my T would be upset with me. That he would think I'm outside of his expertise.
I wish your T would've at least spoken to you in person. Terminating you over the phone was wrong and I hope she gave you some referrals. Did you get any referrals or direction? You didn't do anything wrong and didn't deserve that. You do deserve to have a new T who is able to help you through this right now
