I lost mine 2 years ago.
Unbeknownst to me, my mother was the connection between myself and the rest of the family.
With her now gone all my relatives have disappeared.
They have their own lives, and I’m not part of it any longer since the one thing we had in common is gone.
Maybe take time to appreciate how much your mother benefitted from you looking out for her, and take a break from the news if possible. It can be an addiction. A friend of mine calls it tragedy porn.
