Nobody’s head follows a textbook. If it did, we would be called robots, not humans.
You could argue that we’re nothing more than a colony of ants buzzing about, erroneously feeling independent.
I suppose in the grandest possible scheme of things, our individuality disappears from view. If you are an alien looking down on planet Earth from afar.
But it still exists, and for you, here, on Earth, it counts.
Our individualities produce the innovations which further (and destroy) our race.
The fact that your brain doesn’t work exactly the same way as mine is a necessity.
That’s why providing everyone consistent mental health is difficult.
Knowing that the individualities inside your head are a necessary part of being human probably won’t easy your suffering.
Recognizing that it’s not your fault, might.
