At the end of the day you have to understand some people are mentally ill like really really mentally ill on a level you can’t understand. I see this a lot when someone does something weird or incomprehensible and people are shocked trying to figure out their intentions and why they’d do it and it’s like there’s people who are psychotic or delusional or have rapid mood swings you’ll never be able to comprehend and very often people with other mental illnesses who are able to function more acceptably have a bad lack of understanding of that and compare what they can do and act like as the standard not understanding that’s not the same playing field
People facing addiction, eating disorders, abuse, etc as well will do things you’ll never understand. Getting in the habit of not judging or at the very least not making the lives people who aren’t harming you worse, is actually, a pretty good thing to do
