Depressed people see the world as it is more accurately than non depressed people. It's called depressive reality. When not depressed, we put this colorful glasses and see the world through them. Society doesn't help people proactively, unfortunately, but re-actively (even then, it fails in my opinion because of the lack of empathy). If people waited for help while in their isolation or sickness, probably they would die and no one would know or even care. Sad but true. The question is: given this harsh reality, what we can do to adjust to it? Obviously we cannot change it.
