I have multiple ones for you, the movie and book - It's Kind of a Funny Story by Ned Vizzini, Sticks and Stones: Defeating the Culture of Bullying and Rediscovering the Power of Character and Empathy by Emily Bazelon, Conquering Venus by Vanilla Heart, Cyberbully (movie) by Disney, By the Time You Read This , I'll Be Dead by Julie Ann Peters, Bait by Alex Sanchez, Suicide Notes by Michael Thomas Ford, Parrotfish by Ellen Wittlinger, etc. If you are depressed and/or suicidal please talk to someone and call the suicide hotline - 1-800-273-8255.
A good movie I have seen is Cyberbully. Its an ABC Family movie and if you have Netflix you can watch it on there. Its main character is Emily Osment. It shows how you have to be careful what you post online and it goes from just cyberbullying to being bullied offline. It also shows how being bullied can really affect someone and how bullying goes along with suicide.
