I am not American, but my country has been going through some rough "historical times" itself, and at the moment I have no shred of patriotism left in me, my government would probably want me jailed for multiple things (little, petty, freedom-of-speech-non-existent things, nothing actually criminal) if someone so small and insignificant as me ever caught their attention, and the future is so uncertain that I honestly have no idea what I'm even trying to move forward for. The fact that I can be out of work practically any moment now (and what I do have barely pays my bills check to check) doesn't instill much confidence either.
But I do keep moving anyway, 'cause I'm too stubborn and also I have to believe that things will get better. Much like you, I'm way too young to be a doomer, and after every down there has to be an up eventually. Just gotta hold on.
Sorry to dump all that on you, I guess it's just my way of saying "Hey, can relate! You're not alone!". Your next drink is on me.
And for the record, while yes, the world is kinda mean, and we humans are capable of some horrible things, we're also undoubtedly capable of so much good. Those people running community help organizations, protesters trying to make change despite the risks, soldiers refusing to fight unjust wars and deserting, volunteers helping old folks and animals, little acts of kindness, etc. It's hard to be kind and hopeful and selfless when the world is burning, but a lot of people still choose to be so. That has to be worth something. I have to value them more than a bunch of those powerful of this world, even if their impacts are... often tragically different.
Everything changes so fast, no one can tell where we'll be in thirty years even. Let's believe it'll be a kinder world somehow and may we be strong to do everything in our power to get there.
