like holy shit the bourgeoisie are trying to kill us all actively en masse within our lifetimes and all movement against it feels like it has died come the 20s. Every time it gets brought up it feels like people are either revelling in it, are denying it, are too tired to care, say “someone’s going to fix it so there’s no point in worrying," or get angry asking “well what do you want me to do about it I can’t fix it” or something. It feels like we’re in a moment where we have just abandoned science all together in the decaying west, so the plan is almost like to keep attacking the biosphere out of spite for everyone around us.
It feels Lovecraftian, I can’t think about it because every time I do it paralyzes me in awe of the urgency and scope of what has to be done. Do I just stop thinking about it? I guess the answer is to keep organizing but I’m scared that we don’t have enough time at this rate to address it before it gets catastrophic and has irreversible effects

The only real solution to your issue is to just not think about it I’m afraid.
There’s patchwork solutions that aid in not thinking about it - Preparing for what comes, organizing so you feel like you’re doing some good, working to alleviate the worst of it, learning about nice things that are happening (mainly in China).
You’ll still end up thinking about it from time to time. You’ll still be paralyzed. Hopefully it will be easier to break out of with some of these.
I’ve never met a mentally healthy person who was aware of what lies in store for us. I’ve never met a mentally healthy person who was thinking about it.
Dread and paralysis are two very separate things.
If you know what to do (especially day-to-day) and have the will to do it, you’re not going to be paralyzed, even in the face of terror.
