1) i realized some time ago that alot of social media, with whatever algorithm they use, will try their best to push whats most popular to you. No matter if it’s positive or negative. So while Im on insta, I tend to delete the app and redownload it a day later when I catch them doing that. It’s like a mini reset but not really. But alongside that, i have made the conscious effort not to doomscroll and to dislike and report posts/comments/videos that are willfully harmful and spread misinformation.
2) i look back into the areas where i spent a lot of time online as a child when i didn’t have social media. And that place was Youtube and rewatching comfort shows and finding new outlets that don't trigger me. Sometimes that’s finding people online that only have like 5k subscribers. The other well known site that doesn’t have awful people on there is Pinterest 😂 i never had an awful time on there outside of the ads
3) like i am the child of the house, i limit the content on my phone. On the Iphone at least you can set timers to how long you have been on an app each day and block certain websites.
