One person I know is the victim of child abuse, has been depressed for years, self-harms, and has attempted suicide several times in the last month.
I'm pretty well off, and I always have been. I have a caring family and concerned friends. I've only been depressed for a bit over a month. I don't self-harm, and I've never actually attempted suicide. I have food and clean water. I live in a stable household. I can drive wherever I need to in my car. I've got a computer and a smart phone for playing games and connecting to the world. Those things are great.
But I'm still depressed, and just because I don't have you anymore. Absolutism just doesn't apply to depression. I don't care about anything but you right now, so the pain of people whose depression is more justified doesn't matter to me. All I can feel is my sadness, emptiness, and longing, not theirs.
And I can't feel your anxiety and fear. But you are still the only thing that matters to me so, even if I can't feel your anxiety, it still matters to me. At least you're better off than I am; I care about nothing except you, while you care about everything except me.
