So, if I'm understanding, it hurts you to keep this secret, but fear and guilt keep you from revealing it? Is the fear and guilt reasonable? By that I mean, would it violate a value you believe in to tell? Is that what the guilt is about? Is the fear from the past, the present, or about the future, if you were to tell?

I never revealed my abuse publicly, nor confronted my abusers. I had no reason to believe anyone else had been or would be at risk, so I saw it as a private matter. While I never forgave my abusers, I also didn't feel any purpose would be served for me to engage in such a confrontation. I was able to heal sufficiently through therapy, and I just didn't see any gain to telling beyond that. It sounds like your T believes keeping your secret (I still don't like the word as it seems shame-based to me) is actively hurting you and putting you at risk. Is there any way that you can hold to your decision, but with less fear and guilt attached? I hope so.
