In the book "Extremely Loud and Incredibly Close", Jonathan Safran Foer's post-9/11 story, the young narrator describes his sadness as being like wearing "heavy boots." That is how these days feel. All we can do is try to continue to work in some way and be kind to ourselves and each other.
I hope that you are finding solace in your art materials. Grab some crayons and let yourself be a kid. Don't worry about what you make, just make something. Just move forward, in your heavy boots.
