My T's take on this for me was that the objective detailed recollection--which would probably never happen-- wasn't necessary to heal from the emotional consequences. That the emotions would have morphed as I grew, that it's the nature of emotional development to incorporate prior emotional experience. So healing the emotions from the experiences I did remember was just as complete as if I'd remembered every day of my life. The "partial" narrative is no less true emotionally than a "complete" narrative. It helped me feel settled and whole, despite huge gaps in memory.
