Can anyone tell me how to tell the difference between these two?They seem to have very similar effects; constant fatigue, lack of sleep, detachment from reality, lack of focus/concentration, that hazy dreamlike feeling all the time. I know that there is something wrong, but I'd really like to try and pinpoint it. My shrink is just treating me for depression and anxiety, but I really feel it is deprivation or DPD, only problem is that im pretty broke and can only afford to go to the county clinic which doesnt have a sleep specialist or a DPD specialist. If anyone can give some insight Id appreciate it. Thanks
