You experienced what happened as trauma. Whether or not your T views it this way doesn't really matter. She may have her own reasons why she doesn't, or just has a theoretical orientation that favors your current life functioning. It sounds like your beliefs and behaviors have recovered from this experience; but that doesn't necessarily take away the power of the memory of it. Cognitively, they're in different parts of your brain. One doesn't automatically connect to the other. Maybe you need some intervention by someone trained to address this, in addition to your regular T work. It may not take a lot of time, either.
