I believe the way it all goes down looks a little something like this...
ADD/ADhD --> leads to Anxiety. And most likely a co-existing anxiety disorder that often manifests for two reasons. 1. Anxiety actually aides attention. So like, your brain figured-out it could best assist Magic Qwan in navigating the world and doing all that needs to be done if it kept itself attentive by remaining in a perpetually fearful/anxious state. And 2. Anxiety developed out of feelings of inadequately (merely knowing you are not able to do the things others can do as effortlessly, etc.)
Anxiety --> Chronic Fatigue syndrome. Unusually high levels of the stress hormone cortisol (fight or flight) in an individual's system over time will eventually shut that person's body down and is what medical professionals believe is one of the main contributing factors in the development/onset of CFS.
CFS --> major brain fog and spacing out (so not helpful to someone with ADD/ADhD)...which will be made a hundred times worse if you have depression on top of that. And it's worse in the morning until some other hormone kicks-in I believe but I don't know for certain if that's accurate or what hormone it is if I'm right in that regard.
Now if I've actually gotten my shit together enough to drive somewhere and am around people, etc. then I'm not inclined to space out at the levels you report which is why I mention depression. I definitely believe you are suffering from depression...and because I also believe you are an e7...I think depression has a way of 'escaping' you just like it 'escapes' so many other e7s...making it nearly impossible really to understand the extent of it...the severity of its impact, etc. And subsequently difficult to address.
