"The things you think about determine the quality of your mind. Your soul takes on the colour of your thoughts." Consider not taking in so much war content, you'll feel better!
This applies to the internet also. Nuke as many social media and other services as possible. It's only anecdotal evidence, but I notice I experience much more general happiness now that I use the internet a lot less. I have linkedin and nostr, and even those I only use occasionally.
