I'd like to add my two cents if that's all right.
I frequently visit the place where it happened, however, I have yet to be able to step into that room. I would say that 80% of it took place at my father's home, in our bedroom. I never feel comfortable when I'm there and avoid certain parts of the house.
But I think if I were able to open that door I would realize that it's over, and as Gary said, it would help me to re-gain some lost power. But I'm afraid that if I open that door I'll realize just how bad it was and that it was real. I'm not strong enough to face it.
Daryl, thank you for starting this, it's something I have thought about but never investigated.
