Glad it works for you, but doesn't sound like a generally applicabale approach.

I really disagree with a couple of your statements: "The way to properly deal with trauma" there really isn't a proper way imo. Individuals have different ways.

"will guarantee that the emotional reaction will come roaring back to the surface when some strange, probably unrelated situation triggers the memory once again." Not really true, not always. People do successfully repress, and some people have a really negative experience from treatments like the one you suggested.

People are different and their experiences are different.
