Media is so skewed and biased, no matter where you turn. I think of the orders of contemplative nuns that never listen to news but whose prayers uphold the world.
For us who live in the real world, we do need balance. Remember that the best way to bring the world closer to God is to work on your own sanctity as a priority, then also help others to the extent you can. Prayer is extremely efficacious for others.
I always have so much to pray for and can’t possibly pray for all the world’s and individual’s needs. I don’t think we need to do more than implore God, in a general way, to have mercy on all, especially those who most need his mercy.
And yes, vote and participate in politics to the extent you are called to do so. Many of us are not called to do so but that doesn’t mean we aren’t “doing” something.
