Years ago if you had a bad day at school you came home, did other things and worked through it. If you are a target for attack on social media and cannot abandon it you will never escape it. Whether it is "the mean girls" or stalkers or really evil and harmful people you can go there 24/7 and be made to feel miserable. Some kids have committed suicide because of it. How healthy is that for anyone let alone vulnerable teens who live and die by the comments of the peers? Know anyone who has been irreparably harmed by words? It isn't the words that harm. It is how the target reacts to them that is the problem.
