I understand there are websites which wickedly inform young people how to kill themselves, and which glorify suicide, making a type of cult out of it. If a teenager is depressed, disturbed, in turmoil etc, these sites could be literally lethal.
Very interesting to consider the possibility of a malfunction of the brain in some cases. I'm so very sorry for the parents of teenagers who have ended their young lives like this. However can they come to terms with it?
