Oh, sw. That sounds so painful.

I agree that you shouldn't look at this as you doing something wrong, and it does sound like you an T will move past this rupture. T's are indeed human, and your T was definitely showing you her hurt human side. But it's good to express your feelings to others and then learn to work through that conflict. I can appreciate your T asking you to do it in session, though, and not through email. I have to say that this makes me glad that my T doesn't accept email, as I might be tempted and send something I'd later regret, or I'd completely obsess as I waited for T to respond.
It will get better!!! You took the first step, it will get easier.
