I do tend to "pass out" around eight P.M. most nights as of late, though I would attribute this more to the effects of being hypersensitive and hyperemotional than trying to figuring the world out.
On a smart-phone, some applications, such as the Picture app, drain the phone battery much more slowly than, say, a Video app. My brain seems to process the world more through video-type apps than picture-type apps, which causes it to deplete more quickly.
It may also be that I am running too many applications at a time; on top of any application (Reading App, Writing App, Test Performance App, Social App, Avoid Having Meltdown App, Hunger App, ect.) that I may be running at any given time, I also run the Imaginary World/Maladaptive Daydreaming App (which is ike a 3-D, high-definition gaming app), which also drains the battery more quickly.
League_Girl, your experience with school sounds absolutely horrendous--no child should have to do schoolwork nearly all of their waking hours! Sadly, the Common Core in the United States is causing more and more of this, from what I have read...
