Depression is more than just sadness. Sadness is something that everyone faces. Sadness is an aspect of depression, but not the totality.
Depression makes it difficult to feel positively about future prospects. Depression makes it difficult to emotionally invest in anything, even things that once held your interest. Depression makes you miserably lonely but makes you feel unable/unwilling to seek out human contact.
Nothing feels right. Everything feels like it doesn’t matter and yet matters more than anything. You feel too depressed to do things and then you feel depressed about the things you didn’t do. It’s vicious. It’s cyclic. It’s unrelenting. It goes much deeper than mere pessimism or sadness. It’s a form of psychologically paralysis.
You feel crippled inside. And no one else can see it. No one sees the invisible barrier that prevents you from being who you want to be. Even these words truly fail to capture how it feels. Only those who have experienced it or are currently experiencing it will truly understand.”
