There is a consideration that has some truth to it. However, it must first be put into context. It concerns only purely mental disorders. If physical defects are also included, it no longer fits. This can be the case if mental complaints in consequence trigger a physical defect. The cause of mental discomfort, such as depression, can be a disillusionment. A disillusionment is actually a good thing. dis-illusion. So a disillusion is uncovered and thus recognized as an illusion (lie). But for most, this leads to grief. The grief is not the real problem, because it is part of overcoming a dis-illusion. The problem is that the grief is not recognized as part of the dis-illusion, because possible the dis-illusion is not recognized, so possibly even subconscious. Most people do not begin to grieve in a dis-illusion and thus cope with the situation, but want to maintain the illusion. This leads to an (inner) conflict. Everything goes wrong. The dis-illusion does not become an actual joyful event, where only the loss of the illusion is mourned, but becomes a pain. However, the matter is so deepened in the society, because disillusionment is to be avoided absolutely, that most people have no chance at all to look at the matter from another point of view. This leads to immense stress, which makes the whole situation even worse. Also the approach to look at the matter from another point of view, the dis-illusion, is rejected by many people from the beginning. Rather, they build on it to make a real disease out of it. This gives them something to hold on to and with which they can explain a lot of things to themselves, that above all it is mostly the others who are to blame (and overburden them with the situation). However, the others are only to blame insofar as they were the deceivers. However, this consideration should be used with caution. For it is not true that everyone is to blame for their own mental suffering. It is much more complex. Some cannot even perceive the dis-illusion, because it takes place subconsciously. It may (not must) help to look at a mental disorder like depression from the perspective of dis-illusion. However, most of the time the matter is so complex that this helps only partially, but at least somewhat. An illusion can be that there was an idea of something that could not be kept. For example, a disappointed love. Or a failure at work or in the family. However, it can also be that the illusion as well as dis-illusion lies hidden in childhood. There are already some people who say, yes, disillusion is a part of my mental disorder.
