Chaotic,

I see the email exchange as a good step forward. It helps you see that what you try to tell your t is somehow lost in translation, either because you haven't been specific enough in describing your issues, or because she is somehow not "getting it." Now you can think about ways you might divulge just a little bit more in a way that feels safe for you. It's really your call how much you want to tell her, or if you want to say anything about certain subjects. But if discussing it in more detail is necessary in order to rid yourself of pain or shame, it will benefit you to think about how you and t might begin doing this in small steps.
