Have you discussed this with your present therapist? I have memories that are kept with a few parts. These parts say I am still not ready to see them. It is frustrating but until they think I can handle them they are not going to let me see. I have had quick flashes of some stuff that happened to me when I was three. And I have a sort of narrative in my head that lets me know something happened to me when I was three, But that is it. So bottom line according to my parts (which is me) I am not ready. I still need to build a stronger inner self so I can remember, and than go forward to heal. I will be able to know once I can over come the fear of knowing. Take care.
