Severe Memory Loss

hi, um, i havent posted here before, but after many therapy sessions, me and my therapist think i have CPTSD. i have a really bad problem, where i have trouble moving on from the trauma that i went through in the past, and part of, if not most of that is due to my inability to remember some parts of my trauma. I have been told some parts of my trauma, have had flashbacks and memories resurface of others, but i still feel like there is a lot more that is buried there. i feel tethered to it, and i dont know why. Has anyone else experienced CPTSD this way, and if so, is there any advice you have for someone who is struggling with that right now?
