I understand precisley what you mean. It 'got' to me months ago when Russia and Ukraine were constantly on the news, I was waking up all hours to check on my phone the latest news until I said stop to myself and i made a conscientious decision to watch the news once a day.
Maybe you could make that decision to yourself, watch the news far less, whatever you think is best, but limit the amount. I do understand your worry but there is absolutely nothing we can do, all thats happening is that we are making ourselves ill.
Take care 
That is the crux of the matter for me, there is absolutely nothing we can do….?♀️…I have to stop watching completely because I know if I start reading headlines I will go right into it so I’ve just deleted the news app on my iPad and my phone… when I was younger I never ever watched the news, had no idea what was going on and probably all the better for it…
