It's the point of no return for something, but I suspect there's still a future to fight for. Anyone pushing a full doomer view is trying to suppress you. In case the worst happens, you should try to build a community around yourself and support other people. Join a mutual aid group if you can (or start one). If you grow produce or something, talk to your neighbors and exchange resources.
If we build a strong foundation, nothing that happens can break us. In the worst case, they'll try to break us and break themselves upon us. We need to be strong so we can come back stronger in the future.
I sure as fuck am. That being said, before I check out of this world, I guarantee you I will wear a rich man's skin as a suit. They will not just get off without any consequences for the horrors they have created.
