I have read some about this, and and have seen at least fragments of it in my friend's situation that compare to what RCR describes with her situation.
The history that was re-written does start to become positive again, gradually. In the beginning, and at the height of the crisis, I have often seen (and heard) the word hopeless to decribe the feelings of the MLCer. In one of Conway's books, it describes depression with several words....two of which are negative and hopeless. It goes on to say that the past looks dreadful to the MLCer, making the present and future both seem hopeless....but because they are in denial, the MLCer typically tries changing so many things.....body, job, spouse, and belief system.
In my friend's situation, there was something his ex-wife mentioned a few times around bomb drop and was very negative about it. About 2.5 years later, she told him she wished they could go back to that time.....her memories of that time were starting to become positive again.
I believe that as the depression lifts, the MLCer more clearly sees the strength of the LBS. I don't think the connection between the MLCer and LBS ever really goes away.....that may be why some MLCers are boomerangers. As the depression and denial start to lift, which as Conway describes is a gradual process, the memories that were so clouded in negativity begin to become positive again.
Just my thoughts and perceptions.
