I don't remember consciously what date my rape occurred. I cannot even for sure say what season it occurred in, but I suspect the springtime. I have no proof of this though, and not the slightest memory that would substantiate it. It is just an inkling, now that I think about it.
I got sick all last WINTER, though, so who knows. The winter before that, I was not sick, however, and the rape occurred many years ago now.
It may depend upon the person, it may depend upon whether they suppress the memory or they ponder it deeply, who knows. Each person is different. However, I do believe that if a person believes strongly that the anniversary date(s) will affect them badly, probably they will. I also believe if the person strongly believes that they won't, and puts a lot of energy into making sure that they don't, it is possible that they will indeed be affected by them anyway. It is just a thought.
