Social media and on demand media hijack the emotional triggers that would usually be resolved by talking to people. Some examples:

* In line at the BMV, bored and feeling lonely. Should resolve loneliness by talking to strangers in line... mostly chit-chat, but sometimes you make a friend! Social media turns this into doom scrolling.

* Sitting in the living room by yourself, feeling a little lonely. Should result in calling up a friend or relative, or heading to get a coffee/beer where you can interact with people. On demand media turns this into low risk watching shows (yes, old school TV was an option, but on demand, there's always something on that is interesting).

So the trick is to make yourself ask if you should give someone a call or go somewhere public when you are pulling out the phone with intent to scroll or watch a show. When you find something you are interested in because you are watching lots of videos about it, or replying on forums, force yourself to engage in the real world. If you are arguing politics, find a group advocating your position and get involved (I've got to meet three majority leaders and two Presidents, plus a bunch of congresspeople you see on the news all the time as a side effect of getting involved because I was pissed off on the internet about business taxation issues). If you find a hobby, find a local group that does that. Learning to play the guitar from YouTube was fun, but jamming with other musicians? Off the charts fun and far more educational that just playing along with videos.

Finally, and this is the big one, try to never eat meals alone. Never say no to going to lunch with coworkers. Join stuff that meets for breakfast. Dinners are hard, but it's surprising what happens when you invite a couple people over for dinner and a beer once in a while.
