Some people have real problems, like PTSD from wars where real people really die. Anyone who equates social media to that is being either weak, or unserious, or simply incapable of dealing with life. People need to get a grip. Remember that anything you feel from a social media interaction is self-inflicted -- it is your own reaction to what you saw.
This. Social media is not heroin or crack cocaine. If you, as an adult, are getting fulfillment and dopamine through screaming at people on the internet, instead of the life you've established and the interactions you have in it, you are a TOTAL failure.
The reason why it's so 'hard' for these people to quit, is that they absolutely refuse to accept that they are at fault and need to seriously rethink their lives.
