I would perhaps identify the cause, there is so much doom / gloom in the news then avoiding the news or just watching at specific times may help, it is still important to keep up with some current affairs.
As for social media, that has a known negative impact on mental heath.
So in essence grab back control and limit exposure, while others are glued to the news, then social media to discuss, you can go out or do a hobby you like, get some fresh air and get away from the constant barrage of negativity.
