I'm sorry this is so hard. But it doesn't sound like you "broke" your therapist at all. It sounds like she has some other serious things going on, and work in general is just too much for her right now. As much as we think everything in our therapy is about us, the therapist is also nothing else but quite human, and their own issues and problems can cause them to reach a place where they just don't feel effective. At least you have a therapist able and ethical enough to know that she is not effective in her current state.

Be gentle with yourself. She seems care deeply about your well being.
