Well, not everyone’s endeavors fail. Many people have found their way out of their problem and have shared their “cures” in the recovery section. Whether or not a person recovers from DPDR depends on several factors, including how long he has had it, how severe it is, what the nature (cause or reasons) are for his experience, and what resources he has available to him. Some people find total “cures,” some people find partial recovery, and others find some way to make this experience tolerable or even in some way beneficial for them.
It may be the case that, for some of us, DPDR will never go away, perhaps due to some undiscovered and incurable structural problem, or perhaps because we’ve just gotten “used” to experiencing ourselves this way that we are simply unable to perceive things the way they used to be.
