A few months ago I found a video on YouTube called Bullycide and posted an article with the video. It seems like the term Bullycide is becoming a more common term used to describe when a young person commits suicide after being bullied where the choice they made seems tied to the bullying they received.
I just found this web link to a book called Bullycide In America. The book is compilation of letters and stories from parents who have lost their child to suicide due to bullying. Brenda High, founder and co-director of Bully Police, USA, Inc. compiled the book.
She should know quite a bit about this subject, because she lost her son, Jared to suicide from the effects of bullying in 1998. Her site www.jaredstory.com tells her story in a compelling and moving way. If interested, take a look at this book and the other support offerings from the Bully Police website.
