I feel like that's the downside of social media in general, like the network effect - since most people are on social media, that's the place where people will post life updates, as opposed to talking to others about that stuff directly as much.
Maybe there could be a healthy way to use social media: to catch up with the people in your social circle, maybe look at a few cute pictures of animals or memes, but don't obsessively doomscroll or compare yourself to the highlights of others' lives.
