Hello,
You experienced something extremely traumatic... Unfortunately in today's world it happens all too often. I know you asked for rape victims only, but I have treated MANY of them in my office (Psychologist).
Let me give this two you in two views, one scientific, one from the heart.
Scientific:
After an event traumatic enough to trigger the neural receptacles in your brain that enact the fight, or flight sensation within you, your mind will be offloading short term memory, and committing it to every sense you have at the time. Your brain then commits every detail to long term memory and begins replaying it. It replays the emotional response to the event every time to harden itself in what most scientists believe, preparation for the next time it were to happen. There are only a few ways to stop this from happening. First is the worst, letting it replay until the body triggers the creation of a linkage cell that will block the traffic creating these feelings. Second is better, that is forming a baseline understanding of how and why it happened, along with recognizing the odds of it happening again. Third, is the best (from a scientific standpoint) and that is using the drug Citalopram... Controlling the flow of hormones within the brain.
From the heart:
Nothing can take back what happened to you, but no matter how bad the scenario that life throws at you, it isn't worth living unhappy the rest of your life. Every human being deserves to enjoy their life and you simply can't do that while hanging on to the pain in your past. I have been a Psychologist for 25 years and I can tell you I have hundreds of cases like yours, every person who's had this same pain in their life has found comfort in happiness in that they still get to live a life of their choosing. It will fade into the darkness of your mind as nothing but a distant memory so long as you can make the decision, to not let it bother you, to not let what that person did haunt you. You let go of the memory for you, not for them, for you to show to yourself that you will fight for your happy life and win, no matter what.
My wife wanted to add to this:
What youve gone through I have been through as well. My husbands advice is difficult to understand at first, it seems like he is preaching something that isnt possible but it really is. Take comfort in knowing that others have done the same and you owe it to yourself to get that happiness you want. I am sorry you had to go through this but you are not alone. You can be happy again, and it really is a matter of knowing you can move on, knowing you are stronger than the pain that was given to you.
We both wish you the best from the bottom of our hearts and will keep you in our prayers.
