We really do live in a society, huh? 
You'd think I'd be numb to all this shit by now. But I'm just sad.
We broke the 2-degree threshold in global temperature increases recently. Media shrugs.
Covid spike yet again. The media tells us to harden up or die.
Everything fuckng sucks. Wages suck, prices suck.
The people protest, they rightfully don't want to boil from climate change or the genocide of Palestinians. The capitalist government says fuck you and arrests them. Very cool and democratic.
Death, disease, poverty. Everything is falling apart. I feel powerless. Like I'm watching the murder of something beautiful and all I can do is watch. The powers in charge of this are monsters. All they seem to want to do is make everything worse and anyone who doesn't agree with fucking up literally everything is labeled an extremist.
Shits traumatic.
I am writing this for myself, just as much for all of you.
It was always going to end like this, I think. Humanity has been seeing it coming for decades, before we were born, about the ultimate fate of humanity under capitalism. You could see it in dystopian movies, fiction, novels, shows. You could see it in revival and popularity of nostalgia. Of fantasies of escapism.
Death has always been inevitable. Societies were never eternal or immortal. They die. When they die, it can be self-inflicted. It can be because of events out of their control.
It doesn't mean that our lives were meaningless or tragic. It means that the end of the world is the end of the world as we know it. Will we go extinct sooner or later is not the negation of meaning but understanding that life must be created with meaning.
We'll persist even if the ecosystem becomes as hostile to life as the rest of the cosmos are.
A religious anecdote:
The prophet, Jeremiah, was prophesizing and consoling the Israelites, in the verge of destruction and oblivion by Nebuchadnezzar, of redemption and renewal. That God had still loved them, and that despite the hardship at the hands of Babylon, God would be with them and protect them even in exile. God is within our hearts and home and we will always be loved even in the face, as Jeremiah witnessed, of annihilation.
The point is, you should not give in to despair but embrace the absurdity and beauty of life all the same. You can't really be sane when you are hoping and fighting against overwhelming odds and fatigue of war, hunger, disease, poverty, oppression, age, and heartbreak.
Your heart must triumph over your mind and exclaim the opposite of what your reason dictates. You have to just say "Fuck you" to all that.
The ultimate act of defiant happiness is to live. With all that encompasses, for good and for ill, for excitement and banality, for love and for disdain, for self-actualization and reconciliation with your own humanity and connection with others.
If we're all going to hell, then bring marshmallows.
This particular track from FFXIV carries those vibes and I was hearing it in my head while reading your post. (CW: Endwalker spoilers)
