But no one ever listens. People who post stories about how they "quit social media and never felt better" get tons of attention because most people recognized that social media is bad for them. But just like a drug, everyone is aware of these feelings but never listens to them. Those posts also remind people of their bad relationship with social media which puts them in an even deeper spell of unhappiness. So, in order to feel better about themselves they go on Facebook and watch Dude Perfect videos until they're numb.
Here is some unsolicited advice: just stop. That's it. It's the same with other forms of addiction (with the exception of drugs that can kill when you go cold turky. Luckily, social media is not one of them), you just stop doing them. What do they do in rehabilitation? They distract you from thoughts about drugs and try to create other avenues for you to get the reward mechanisms drugs gave you before. But really all that boils down to is you just stopping and moving on.
