If your fear for the future prevents you to live your present life, you don't need more arguments with strangers on the net. You need professional help and I hope you have it. Doomerism may not be an illness, but depression is, and like all illnesses it's better to fight it with a doctor. Believe someone who suffered it, and married to someone for whom it's chronic. There is a way out of depression too, or at least a way to mitigate its effects. Just like climate change.
