Just an Australian thing Evie... the way we speak I guess.
Rob, nothing wrong with being honest mate, that is exactly what you want to be, especially with yourself. Ok, so you likely hit it on the head with the sexual abuse, though don't for a second think you can "get over it", because you will never just get over it, you will come to terms with it, completely different outcome and approaches. One is like beating your head against the wall, the other has a more logical path with an acceptable and realistic outcome.
What you must differentiate now though IMO, is that your surroundings and lifestyle have completely changed since your abuse. Your nothing like the same person, even though you mind sometimes wants you to be, your not. What you fear is your past, not your present. I doubt you fear the kids, but more what the kids stand for. Sure, if the kids pulled a knife or gun out, then you may have something to fear, but I believe the actual fear is off your past trauma... and I believe you know this anyway, as from your statements above.
This is an area I believe you really need to work on Rob... you see, you have to accept that you are the victim, and its perfectly ok to be the victim. Being a victim doesn't make you weak, far far from it, it simply means you where over-powered and forced to do something that no person has the right to engage without permission. Its like a person saying they deserved to be raped, if only they did something differently, if only they weren't drinking, if only their dress wasn't so short, etc etc.... all factors not attributable to blame or guilt, but instead a persons right to drink, wear a short dress or clothing of choice, enjoy themselves though never did they ask to be raped. Nobody asks to be raped.
A person once said to me that they did ask to be raped, being in a sexual situation, though the negation of rape was eliminated the moment they "asked" for sexual contact, as it was consential. What they meant was really they wanted forced, rough sex, not to be raped against their will.
NOBODY ASKS TO BE RAPED, EVER.
