I thought this article could be helpful for you about Memory Reconsolidation.
It is about treatment of drug addicts, but the treatment can be applied to memories of abuse in survivors. The bottom line is that repressing memories make them come back stronger later on. Retrieving memories, working on them, releasing them can permanently change their impact on the person.

"Research has shown that memories can be changed more permanently if they are retrieved first," David Epstein, a researcher at the National Institute on Drug Abuse in Bethesda, Maryland, told New Scientist. "It is a bit like opening a document on your computer, making some changes, then resaving it."
“Full clinical studies are needed, but it could be really important for treatment of addiction,” Dr. Amy Milton, who researches memory and addiction at the University of Cambridge, told the BBC. “There is no theoretical reason it couldn't apply to other addictions such as alcohol. That's obviously very exciting.”
