Dude, who even knows.
You know the trope of building up to being all pessimistic and worried and convinced the universe hates you but then being fine after you’ve slept on it? Maybe that’s why I’m only sleeping 6 hours now, the other 2 were for recovering that, that’s the exact thing I’m talking about when I say that without the anxiety I don’t feel any worse (or notice, barely, until I’m nodding off) as I get tired.
