There lies the problem! I was the same, 0 energy, chronic fatigue, along with DP/DR.. Was completely braindead .. DP/DR is not about resting your brain, nor crappy term they use "coping mechanism" lol thats completely wrong. You need to WAKE your brain, oversleeping wont help u. You need physical activity, intense physical activity (lifting weights, street workout, pushups, martial arts) to get back to your normal self. I spent really ALOT money on tests, doctors, etc. All that money is wasted, my body was healthy ( although u should do tests to see how you go). You need to wake your brain, and best way to do it is intense workout. In few days, you will be 70% better if you workout hard through the every day. I found pushups to be most effective, do your max, break the limits every day (also take mulitvitamins+minerals specially vitamin D3) and you will be normal. Your brain chemistry is messed probably, like it was in case with me. Intense physical training restart your brain, it simply pump your brain with everything that is good, removing old and producing new. Thats how it works and is definitely fastest and most effective way to remove DP/DR. Although, there are some things that can help develop brain fog/DP for example toxins, heavy metals etc. i You can do mercury test , or u might have candida i dont know. But you can fix even that in just a month with Zeolite + NAC supplementing and healthy eating. Its cheap, you dont need alot money, you just need will. I really wish somebody listen to me im pretty sure 99% of you would recover. Again, i say if you are healthy and tests are fine, this is definitely what will recover you
