It is true...that some MLCer's behavior/actions can push the LBS into a crisis. Just like the MLCer, the LBS will not realize for a while that there is something wrong. Again, it's depression and coping skills that help to trigger a crisis. If you look at the behaviors of someone in depression, their behavior/actions can cause them to do things that they normally wouldn't do. They tend to self medicate to make themselves feel better. Some LBS will go to extremes and others will sleep and become very withdrawn from day to day life. It all depends upon the person. Some people tend to suspect that there is something wrong, but they do not know what it is for a while. Others trying to diagnosis the issues for them doesn't help because those having issues will say that there is nothing wrong w/them. Like an addict, they have to hit bottom before rising once again.
With MLC, there are no clear answers. Why? Because the condition is not recognized by the medical society and each person is unique, their personalities are unique just as their childhoods and coping skills. We can only advise on what is posted here and from our own experiences.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
