I'm not sure about society as a whole, but overall my disclosure of my CSA to individuals has been retraumatizing.
I waited to tell anyone for four years. I decided to tell my mother, because I needed help. Unfortunately, she didn't believe me, asked horrible questions that made me feel to blame, and then the next day dramatically left home. At which point, my father berated me for upsetting my mother, and told me what had happened was not "that bad." (By the way what has happened was I had been strangled and raped by my 7th grade English teacher).
The 1st psychologist I saw, as a teenager, told me I had a personality profile most common among the prison population. She then wanted me to recount my rape. I didn't trust her, so I gave her a very cold, abbreviated version. I feigned better, so I could stop seeing her.
Another psychologist, I saw in adulthood asked when I first knew Mr. G. (the rapist) liked me. I didn't go back to this professional.
One of my ex-boyfriends implied that I had seduced my rapist. One of my friends completely cut me out of her life; mind you I just mentioned I had been raped to explain some of my unusual behavior; I didn't go into any detail.
Radio silence with other professionals and friends.
Other than the psychologist I am currently seeing for these issues, only one other person has reacted with compassion (an ex-boyfriend). Unfortunately, that boyfriend, who actually cried and said he was sorry that had happened to me, strangled me a few years later.
So yeah, I think people pretty much can't handle this kind of information. I'm unsure why, because when someone tells me about being robbed, in a car accident, cancer, or what have you, I respond with care/concern and ask how I can help them. Often, I wait a short while, then give a card, flowers, something to show support. For some reason, though, I'm on my own with these demons that I didn't create.
Thoroughly, unfair. But I guess that's life. At least, that's been my experience.
