I really recommend you watch the movie Bang Bang You’re Dead. It is about a high school student who is bullied so much that he threatens to bomb the school, and sets up a real (but non-working) bomb in his school. Among other things, it is a movie that addresses bullying, suicide, depression, and it really helped me a lot.
Here is the 1st link to the movie on youtube, you have to watch it in 9 parts /:
