I think what RCR says is that and MLCer can show signs of disorders, not that they suffer from any (except depression that is a mood disorder).
Agree, that is written in that my long post. They look like have PD because of long and in time acute depression which become psychoneurosis, then psychosis and if they go out MLC then gradually that start to diminish.
Depression is not, IMO, a reaction. Depression, coupled with stress, is the cause of MLC.
If You carefully read my post You can see that I wrote same. Their persona does not work anymore with outer world. Means coping mechanisms which they use does not work anymore. So, they going into depression. Then they try to get out of depression changing something, unfortunately they start to use maladaptive coping mechanisms instead changing self. That leads in deeper depression, psychoneurosis and how they sink in time they can hit psychosis and their look at the world change FOG, they start to regress = use more primitive defense mechanisms. They are in long chronic depression, which finally hit acute depression. So, then escape and avoid start because they did not solve inner problems which are since childhood, they cannot change, they wanna world accommodate to them.
MLCers external life works fine. Or, at least, several of them can lead what outsiders would consider a normal external life. It is just that they go and live that life with someone else.
I can't agree with that, MLCers 4 pillars are God, Body, Spouse, Job. My wife align with all 4. They just must function, but under persona - mask. They are under covert depression. They wanna change all 4 pillars but they haven't energy and will to do it that make them even more angrier. Ie means, Body = plastic surgery, running, gym, teenager cloths. God, stop to be religious and accuse God for their misery. They get fired from job because they cannot function well in it. My wife change 4 jobs since she go in MLC. Lost interest, low motivation, stubbornness and so on. Spouse is to blame because their life sux and who to blame = SO. My W in beginning blame self = Antihero. When we start to fight about her EA, then she blame me.
So, they are miserable in all 4 pillars, but they have to work and function in life under mask, but they are covertly depressed.
