How do you change thoughts about current affairs/the state of the world? What change of thought is useful with this?

I tend to get discouraged by politics and the many people who I see suffering. I do not want to tell myself it is not effecting me personally. I want to be realistic but hopeful. I am working on this in the model, but I would love any thoughts on how to handle such big ideas. I do not want to entirely avoid the state of things and news that effects so many people. I do try to limit my exposure and work hard to handle my thoughts towards it all. This is a feeling of overwhelm I have experienced since I was young. Thank you in advance for any advice.
