Firstly, welcome to MS. I hope you find this place as useful as I have. There is a countless number of awesome people here and despite the numbers, you will find we each have subtle differences and simalarities in our thoughts and memories.
I am in your boat, though I havent had anyone name me, but consider yourself lucky that your perp at least named you. Many people deny their actions till their grave. You must consider a 20 somethings memory is going to be much better than a young child, the fact he specifically named you is something.
As for memories ive done a whole lot of research and I hope this helps. In short:
1) You may read about "False Memory Syndrome". This is something created by a group of devious lawyers and proffesionals representing accused clients. There is no evidence at all to support that this syndrome exists. Yet some people still peddle it as a possibility. But you tell me whats more likely; an accused person wanting to get out of dodge or someone just 'made it up'.
2) Memories are constructs of your brain. Whilst the basis will be true, some details will be mixed or merged with other events. E.g Imagine you remembered going to a picnic and you remember falling over and hurting yourself. It could be whilst both the picnic and fall happened; they could have occured on two seperate occasions. This doesnt mean the memory is untrue, just mixed. So if you were to remember your own abuse, you may remember it happening on a bed, when infact it occured on a couch. Again, it doesnt mean the memory is false, just the minor details are mixed with other memories.
3) Memories must come themselves. The more you look, the more chance you will get things mixed up. Do not look or scower your mind for these memories , let them come on their own.
4) Memories are associated to senses aswell as emotions. We have this habbit as adults to file our memories under categories. Take a positive sexual experience in adulthood. If i was to ask you about your experiences of sex in adulthood you would easily recall that as it was filed in your brain under "sex". A 5 year old has no idea whats happening is sexual, the concept of sex itself is almost none existant so when a young kid has that experience the memory might be filed under something totally unrelated like "couch" (if it was a couch). This is why people get triggered by certain textures or smells.
5) hypnosis or psychotherapy is a good way to retrieve lost information. But a therapist maybe reluctant to do this if they see no benefit to healing process.
There are others like you, a lot. Im one of them. Your not alone, we are not alone. Keep talking and going.
