We are having the experience of the entire planet being worried about the same problem at the same time. That didn’t even happen in the world wars. This is an unexpected outcome of being a global community.
So I think the thing to do is pay attention to the good part – since it’s a global problem, we have the opportunity to really be neighbors with everyone. And neighbors help each other in deed and in spirit. So doing what we can to take of ourselves and help others as we are able and have opportunity reminds us we are not powerless. Even in response to harshness, we can be kind and that gives us a sense of calm in the knowledge that we can choose our response to things.
And I think grounding yourself both literally and spiritually helps.
