I always felt very confused as a kid that in English class, when we'd read some key piece of literature, we'd be asked to answer why the character felt sad, felt angry, felt betrayed, felt hopeless- and it was supposed to be based on the events that happened to them, their perspective on life, how supported or isolated they were, the whole trajectory of their life's story. But then out in the real world, if I didn't feel happy, it must be a pathology.
You go to the guidance counselor or therapist or psychiatrist and talk about what's going on, and you can tell when they've finished their little checkbox questionnaire and are now just waiting for you to stop talking. It doesn't matter what your mom did or didn't do, what your dad drank, how alone you feel - you're suffering from X syndrome (I personally got told I was Bipolar). It is a lifelong disease with no cure, you're told, and the best you can ever do is cope - you're broken and you always will be, they say in medical-ese. Or perhaps everything is actually fine and you're just being too harsh on your parents - you simply lack character, you ungrateful little brat! And when you can't magically will them into being good parents and you end up feeling bad again, you come to feel like you are broken and always will be on a spiritual level too.
When we observe someone is depressed or having a hard time in life, we don't go back to English class and think about what events in their story might be hurting them, we follow the "science" that they are suffering from a broken brain; we can make a sad face for them, we can say "oh how hard that must be," but at the end of the day, society is still content to exile those people from our lives - after all, they could be dangerous, and nothing is a more popular justification for dehumanizing others than safety, or at a minimum, they will totally bring down the vibes. To really engage with them would shine a light directly into all of those cracks in our system that allow at least 1/7 of our children to experience abuse or neglect (https://www.cdc.gov/violenceprevention/childabuseandneglect/fastfact.html), which really shatters our collective make-believe of being a "civilized" society. That would just be a big distraction from what really matters, like the delay of our Amazon deliveries and how our phone has been getting kinda slow lately.
