Your child is being bullied, what can you tell them?

I saw a recent facebook post where a woman was asking for advice for her daughter who was being bullied at the end of the school year. Her story really hit a home for me because I, too, was bullied when I was in 7th and 8th grade. I remember the horrible feelings of fear and anxiety when I watched my clasmates pass around  a note that said "I hate Judy" and every single perosn in the class signed it. I was lucky in a way becasue this was before social media, so when the paper was thrown out, there was not lasting record of it. I am so glad I am not a child anymore. There are just so many ways to use our words to hurt someone over social media.  We have all heard the stories and have been insensed, but since it wasn't our kid, it's easy to move on. Years later my son was also bullied and we had to shut down his social media and keep him home from school until the matter was settled.  It was a terrible time for our family and many hateful words and rumors were spread. Anyway, I was thinking about what I would tell this young girl from facebook. Obviously, the older me could say that moments like this build character. But I wouldn't want to hear that in middle school and I am sure she doesn't either. I could also tell her that the bullies are weak and lack self-esteem, so they try to make other poeople feel bad so they can feel superior. You should feel sorry for them. Again, useful at 50, not great at 13. 
I want to expand on this idea and maybe shed some valuable light on the issues. If you have an idea, go to my contct page and send it to me. I am sure we can all agree that each child deserves to live thier best life every day and maybe together we can offer words of wisdom and change the path of just one young person.
