T has assured me repeatedly that I can share with her whatever I want/need to with as little or much detail as I feel comfortable with. She tells me that I don't have to worry about her well-being or her coping. Despite the fact, that she hears very graphic stories pretty much on a daily basis, she takes a lot of time in self-care. There would not be a need for me to protect her.
That said, I do worry about that. It's my motherly instincts kicking in, I guess. We will see what happens when I feel ready to share. Knowing myself, I will probably start testing her first by sharing less disgusting things and see how she responds before I have the courage to open up more.
