Well, if you do "meditation" (or "do nothing") in a way that results in shutting down all thoughts except the depressive ones, then it's going to make things worse.
In that case, you might be (temporarily) better off adding some very powerful and addictive thoughts or feelings to cover up the depressive ones; I think this might be in fact one of the main uses of social media and videogames.
Yep, even something mindless like candy crush is probably better than social media. But... what's actually missing for a lot of people is actual community. So many of us live in tiny bubbles in big cities, we crave human interaction... so the lure of social media is powerful. It's actually a miasma of drama (if my family is indication) that appears to shatter actual community, both on and offline, sending people further into their increasingly socially inept bubbles. I wish I had solutions to offer. It's a goddamn mess.
