Perhaps this is just a projection of a square from a non-Euclidean space in which the lines are in fact straight and parallel.
I think the 2D surface of a cone (or double cone) would be an appropriate space, allowing you to construct this shape such that angles and distances around geodesics are conserved in both the space itself and the projected view.
This shape in that space would have four sides of equal length connected by four right angles AND the lines would be geodesics (straight lines) that are parallel.
Once upon a time this happened to me when I had classes. I kept saying I’d get up for the next one and never did (in fact I basically stopped going to class for a week).
I really knew I should go and get out of bed but the more I thought about it, the harder it got.
Eventually, I got medicated, and while sometimes my body tries to stop me from taking my meds, it’s easier to overcome that than it is to get out of bed when executive dysfunction hits.
That’s why I keep my pills right next to my bed and typically I take them immediately when my alarm goes off.
I also set out a protein shake next to them every night so I can eat “breakfast” without having to wait for them to kick in.
Probably not the best solution for everyone, but if you want a suggestion, that’s mine.
Also remember that you’re not alone and while some people might not see the struggle, that doesn’t make it any less valid. Be kind to yourself
