Ditto. From my experience and assumptions by many media I've seen, people tend to post the best of what is going on in their lives to social media. Subsequently, not seeing the bad or mundane in comparison to oneself, causes anxiety. There are many other aspects to the social media that might affect life satisfaction. Time spent on the platform rather than being productive is one that comes to mind.

Unfortunately, I can't say the same. I quit FB a month ago, and sadly not a single "friend" has emailed me or phone called me since then asking "yo, what's up dude?"

If you are upset with the way they treat you, then perhaps you should reconsider your relationship. Have you contacted them? I personally go years without speaking to some of my friends and pick up right where we left off. It feels like there has been no time gap. I do not put much stock in friendship. It would not be upsetting to me if none of my friends contacted me ever again. You may not be the same.
