About climate chanjge, ecological destruction, overpopulation, war, erroding human rights, pending collapse of economy and society, in short "doom"?

I do. I'm wondering how normal or abnormal that is.

Is it an expression of PTSD or is ot a natural response to a dying world and suicidal species that I am pathologising as a form of denial?

Edited to add: I dont mean i burden myself with saving the world. I worry about my personal survival. I worry about seeing and experiencing horrors. My closest friends have evacuated their homes walking by tanks on the road, or been caught in burlap and thrown into prison for nothing, or been hungry and reduces to eating wild grass. My worldview is different because of it, even though my life has been suburban and middle class and pretty sheltered. I was thirty five before I knew an AMERICAN who had seen war outside her AMERICAN window as a child. She was urban and African American of course. The freaking National Guard was shooting at her dad. At her American born dad. My dad would have shot back too.

I am the one generating these apocalyptic thoughts, but why?
