I love that she was there for you after all and understood how much something like that can affect you! It's like a shock and hard to get past, but she kept you there so you could get past it and not have to 'carry' it around with you until another appointment. It is so good to feel the therapist's caring.
And it is such a good experience to end up 'carrying' with us, that shows us how resolving something as soon as possible - in the moment - is very relieving, grounding, and soothing, often very generous.
I'm so glad that a disastrous day turned into a very different day for you!
