If you struggle to disconnect from social media because you feel like you’ll miss out on friends, remember this: If social media is the only thing connecting you to a friend, they aren’t that good of a friend anyway. Your true friends will not disappear if you delete Facebook.
The fear is unjustified. Your actual friends will keep in contact, just like they did before Facebook. I left FB 5+ years ago and by some great miracle I still have a robust social life, and as a bonus am not wasting hours a day scrolling through useless information about the lives of remote acquaintances.
Sure, I have friends like that. I also have friendships that began on social media and endured for years, including both people I've never met in real life due to geographic separation/difficulty of travel and people that I have met and got on with equally well in person. Perhaps you haven't experienced that yet, but I've been hearing this clicheed dismissal of virtual relationships for ~25 years now and it's getting pretty old.
Lastly, not everyone has super rich social life that would make it easy to make and keep friends. Many people work a lot of hours in companies that change every 2 year, limiting opportunities for friends time. Others have children they already feel they spend too little time with. The loose connection when you react to each others posts is much better then comelet cut off.
