I'm glad that you have such a compassionate and caring T! What she said is lovely! My T has also sometimes told me that she is honored that I share with her things that are so difficult and painful to talk about it that I never have before.....and I generally feel about her the way you feel about yours!
Anyway, I'm happy you can talk to her about the SI and that it was a positive experience. Her compassion will be healing for you.
