Just gonna say one more thing:
Haven't you ever been nervous about something, such as having to do a speech in front of a class, or anything like that? Well you probably didn't just make the nervousness go away, did you? You had to struggle through it, and I bet you wish you didn't have to deal with it.
So when kids are bullied, they get depressed, and hate it. They couldn't do anything about it because of their self-esteem. They struggle every day of their life. And after days of endless struggling, they don't want to deal with it anymore, and they kill themselves.
I hope you realize that every kid is different, you don't know their lives. It's not that loving easy as it seems, so leave them alone.
