I don't have anything practical to offer yet, but one thing I have learned over four decades on this planet is that people deal with awful things in two different ways and each group's strategy is unhelpful to the other. One type of people need to focus on the positives to avoid despair, to look for the remaining points of light and the actions they can take now, because focussing on the bad stuff paralyses them and means they can't do anything about it.
