I call it "Nothing matters, everything matters" dilemma.
Every little thing you do has some sort of meaning (even those hours spent debugging) if you choose to give it one.
On the other hand nothing really matters on a large enough scale not the things Bezos, Putin, Musk or any other human does.
Everything is ephemeral as Ecclesiastes already found out.
I think I'd be even more depressed were I put Ozymandias shoes.
