So the night is dark and full of terror? Be a light. However you can. In big ways or small. A thousand tiny gestures of kindness sustained over time will eventually make up a whole. Start somewhere. But don't you ever tell people it's pointless to hope, or to believe in a better world. Don't you dare take that from them. Do better. For your sake as well as others. You deserve better too. Hope is not the reserve of the naive, it is the foundation upon which better things are built. So stop trying to tear it down.
