This is a great article on bullying and I hope you will take the time to read it.
I was bullied by another theme designer a year or more ago. She made horrible threats to me over quite a period of time. Emails and on the old forum.
A Netflix original show to watch is "13 Reasons". It was about teenagers and bullying. If you have Netflix I would advise every teenager and parent should watch it.
Have a good day.
