I relate to this, as historically I am the same way.
Focusing less on Macro stuff (generally things I can't control) has been huge in helping feel positive.
Improve yourself. Be a good friend, father, uncle, whatever. Make people laugh etc. At least in this context a person is having positive impact on everything and everyone around them.
And never let anyone take your ability to be this away from you, even if somehow the worst does come to pass.
