As a person who was sexually assaulted as a child I can say from experience the slightest thing can trigger a memory. My psychologist said it can be a noise, a smell...anything. Something that suddenly reminds you of that horrific experience. I can still 'see' the blanket I was made to lie under. I can still 'feel' it. I hate paquet flooring because that's where I was forced to lay down.
I feel for anyone that has endured this. 60 years later and I'm still suffering the effects while my abuser is still a well respected elder. I did write to him this year and ask for an apology with the full backing of the elders in my congregation who were 'always going to be there for me' Well, he got the letter and didn't reply and suddenly my elders backed off from me. I think he must have pulled strings or something. I asked why and the reply was 'it's your word against his. Nothing we can do. Life is tough sometimes.' If they couldn't do anything then a little bit of spiritual care might have helped but nope, nothing. They distanced themselves from me.
I'm done with it now. No more meetings for me. Not going back. My heart goes out to those suffering.
