I have had moments since March. When it becomes too much, I repeat:
God, grant me the serenity
to accept the things I cannot change,
the courage to change the things I can,
and the wisdom to know the difference.
and then I pray to know what God wants for ME. For MY FAMILY. And those are the things I can change and prepare for. And then I listen and focus on the inspiration that comes, and I act.
The Last Days of this earth are going to be awful and disruptive. Best I can do is listen to God's plan for me and mine, and let the rest go.
Don't know if that helps you, but there is my coping mechanism
