There's a bit in Richard Carlson's stupendously good book, You Can Be Happy No Matter What, where he talks about traumatic events, and really nails it.
The first thing he makes clear is that, in the very, very simplest of terms:
Because if we imagine a life where that past event no longer has any hold over us, and we’re living a happy, peaceful life, then, while we may be able to recall the event, we’ve forgotten the ‘hurt’.
Richard says,
“If we can learn to stop frightening ourselves with our own thoughts, we are on our way to a happier life, irrespective of what we had to go through.”
When we remind ourselves that 100% of our actual experience of life is brought to us via the Principle of Thought, it makes total sense that to heal, is to forget, because ultimately, if it's not there, there's no pain.
