Hi and Merry Christmas back.
I think what she means would be the same as when someone is depressed. If they are suicidal, they cannot comitt suicide until they have enough energy to implement their plan. So in a way, the depression keeps them somewhat safe.
But in MLC, even though it seems terribly slow, there are changes that occur that push them along....I would think a time is reached, perhaps when they first get a glimpse of what they have done, that energy is needed to push them deeper into their inner world so they can finally face what it is that they need to face ( or hit rock bottom) and only then can they start climbing their way out.
Depression clouds all their feelings and abilities to do ore than just survive...with that energy, somehow they will be pushed to a different level..it may be what they need to get to rock bottom because if they do not get there, they will continue to circle in an holding pattern and never progress
just my two cents worth.
