Thanks for the thoughtful reply. I would guess that maybe the peer group is the core of the problem. Probably even most, though of course far from all, teenagers realize that issues they might have with people on social media whom they do not know in real life can be resolved by simply not interacting with them. Maybe social media just makes it easy for the peer group to be present in a person's life almost 18 hours a day instead of as in the past, just a few hours a day usually.
I think that's a big piece of it. I think another part of it is that even /if you/ do not use social media, it doesn't meant others won't post you (including pictures/video) on social media and talk about you. In the past, you might get gossip about who went to what event/party/group activity and who didn't, or what they did, but there wasn't a constant stream of photos and video of said acts and occurrences followed by difficult to impossible to monitor comments made semi-anonymously and possibly exposed without your consent to strangers and third-parties.
It's not just that it can be challenging to deal with your peer group being present in your life constantly, it's that you have little recourse or ways to escape without intentionally withdrawing from your social peer group, especially as a teenager where social media is so embedded in their very existence. As an adult, it's easier, we can be much more intentional about our relationships and lifestyle, but teenagers exist in a microcosm of the larger society, with all of the same problems but without the same recourses.
