When memories of the early childhood sexual abuse that happened to me began to re-emerge later in my adult life, as I first sought therapy, I found a lot of helpful online support from the forums at Pandora's Aquarium (not sure how active that site is nowadays though). Also, maybe have a look The Sexual Healing Journey by Wendy Maltz.

Have you considered trying any body centred work, like trauma focused yoga or TRE to help you process these memories that are coming up for you?
