Mr Rogers said in times of fear or crisis or tragedy look for the helpers.

Kalonymus Kalman Shapira, the Piaseczno Rebbe, also known as the Esh Kodesh, said in times of fear or crisis or tragedy or when you are feeling down BE the helpers, be the people doing good, find someone else who is also hurting or sad or in crisis and find a way to help them.

Take the energy of pain and sadness and use it to help someone else.

That is all we can do right now.
