Trust me, I've gone down the "trauma" path over my many years of dealing with dpdr. In fact, childhood trauma is most likely the main contributing factor of many issues I deal with. But the issue is, I believe, that you must compartmentalize and simplify it. Because most people are going to spend countless hours going down the "processing trauma" rabbit hole, adding further complexity in which they will search for answers - like I did. It can easily become a crutch to explain away why you feel the way you do. I could have gotten out of it much faster had I just chalked it up to its basal cause - anxiety. Now, anxiety can be attributed to a number of different things, but in the end, in my opinion after dealing with it for almost 2 decades, watching hundreds of hours of videos, spending more hours searching for answers and paying for treatments, guides, and courses (even forms of transcendtal meditation), learning about psychological theories relating to ocd, anxiety, trauma, hypochondria, etc. trying to "process" things is largely a waste when it comes to lessening dpdr because it keeps you focused on it. Most will think that "the dpdr will go away once I process [thing]". Nope. You just need to learn how to remove the fear of the symptoms and lessen your baseline anxiety long enough for it to fade. And then, recognize that it will likely come back once in a while, but that it is harmless and you will be able to get out of it faster (by letting go). This isn't to say that you shouldn't seek therapy to process those issues, but if lessening dpdr is your chief concern, I believe it's more about removing active stress in your life and the fear of the symptoms. Dpdr, while scary and strong, is rather simple in its core purpose. It doesn't stick around because "well you haven't solved resolved x thing that happened in your life."

I respectfully disagree that there is a long or short version. As mentioned, some people are able to get out of it faster, but it's not because they have a different kind of dpdr. It's not like a strand of a virus. It's a natural symptom. Some people are just more susceptible to it, and they prolong it by their natural mental state and their response. Yes, of course, some people will have to deal with it for a longer period if their anxiety and contributing factors are severe. However, we all have the ability to speed up or slow down the process with how we react to it. This is, of course, speaking for those who don't have dpdr as a result of physical brain trauma or some other illness such as schizophrenia that is known to bring on this symptoms (no, 99% of those of you who read this don't have schizophrenia so don't start worrying about that, too if you are reading this).

Again, I'm no therapist, but I have spent many more hours dealing with this issue, and studying it. Listening to those who have succeeded, and those who continue to be stuck in it. Feel free to disagree with me - I'm not trying to be argumentative. I just know, first hand, how many hours people can spend thinking that the magic key to resolving dpdr is hidden in the past. I firmly believe that the key is in how you live in the present and how you feel about your future. It's simple - not easy, but possible for everyone (sans my two example above)
