What do you do when you find no joy in anything?

I look in the mirror and ask myself, "What the hell is wrong with you?" If it were possible, I would slap myself across the face too. Hopefully, I'd snap out of it. How could I possibly go through life and pretend that I can't find joy in anything when others are suffering, homeless, starving or in constant danger from a pointless war? There are children dying of cancer. People who have lost loved ones. Victims of crime, disease and totalitarian governments. I'm healthy. In good shape and fully functional. 👍 I have a place to sleep. A few shekels in my wallet. Enough food to feed an army. More books than I will ever have time to read. The dearest friends a person could hope to have and miraculously, they still tolerate my eccentricities. The freedom to pursue my interests and devote some time to worthy causes. This alone is enough to satisfy me. What could bring more joy than voluntarily helping others? If the day should come when I can't / won't find pleasure in anything, you have my permission to kick my a55. Twice.
