Kati Morton has a quote "It's a process , net perfection" and that is so true.
The part about your lecture sounds like the PE therapy, repeating the stressful event until the emotional reaction lessens. It's pretty hard doing that with a trauma event, but I can see the logic in it now. At first it was a "why are you doing this to me" type of reaction and "how can this help bringing up so many other traumas dealing with this one?" Now I have different reactions, I'm bored, get angry that I have to listen to it, so maybe that's a good thing, eh?
