Memories of traumatic events are events in the present. When you remember an incident of sexual victimization, it acts like a shit-happens type of event in the present. The truth is, that memories will not go away, and as you gradually recover from your victimization experiences, they will probably become clearer and more detailed.
Fortunately, it is not the memory, but how you automatically think about the memory that causes the distress emotionally.
Accompanying a memory are all of the traumatic ways of thinking that happened when the victimization was occurring. You can't alter the past, but you can help your own thinking about the past to mature. That is the ticket.
As a general rule of thumb, it is important to deal with the memories of your victimization - to bring them up on purpose and talk about them - hopefully with someone who is tuned into that kind of thing. Professionals call this process "debriefing".
Now, there is no point in bringing up bad memories just so that you can re-live and re-experience the bad times. It is best to hold off on this until you have developed some skills to handle the traumatic thinking patterns that are attached to the memories. Get prepared for this by developing the ability to track down and to work with common garden variety thinking errors and faulty beliefs. Practice your skills on small fare first, before going after the tough stuff.
Some support groups for survivors get stuck in re-playing traumatic experiences over and over again. Others successfully move past that stage. When you decide to go through the pain of remembering, it is better to be able to move forward, to work towards altering habituated, traumatic thinking. Recalling bad experiences can otherwise be like picking at scabs, again and again. Not much healing happens, and it is definitely not the creatively lazy approach.
