I should keep my views to myself but I can't. I find it terribly pathetic that children and adults cannot cop with life so they feel the need to take their own lives regardless of who else they may affect be it friends and family. People persevere through a lot worse shit than that 15 year old who was bullied and still live their lives. Where children are concerned, are they paying attention to their child? If they were that depressed and suicidal wouldn't they show signs?
Well judging by your last sentence being posed as a question.. I'd say you're making a pretty big sweeping statement when you don't even know.
From seeing classmates and friend's family member's commit suicide, there are not always warning signs. Usually the people who killed themselves were faking happiness and one day decided to kill themselves. The people who usually make it blatantly obvious that they need help are the ones looking for attention and a person to tell them not to do it.. when in fact they're probably not going to do it anyway.
When teenagers kill themselves over being bullied, well, let's just say some bullying goes further than you'd think. Not to mention, if a kid kills himself, you have no idea what other problems he was going through. It's not really fair to generalize every suicide.
