Society plays a large role in what our young children feel. A lot of depression and suicidal thoughts stem from dysfunctional homes, but there are too many cases of suicide in loving homes for this to be the main reason. Personally, having grown up in the public school system, I think the emphasis on competition and success plays a large role. When classmates are pitted against one another to compete to get into the best colleges and high schools, even good students begin to feel worthless.
Take Japan for example. Look at the suicide rate. This is a culture that emphasizes success at an early age, and a single test determines whether or not you get a good job. The US job market is growing increasingly competitive, and more an more children are being pushed into extra classes at younger and younger ages. Gone are the days where you can get into a good college on grades alone. You have to do EVERYTHING and volunteer everywhere. This is a stress. Kids aren't permitted to gauge success on what they learn. Rather, it's based on results and tests. THAT is why so many feel so lost. They can be a straight A student, but feel worthless because another student got into an exclusive school that they were rejected from.
Child suicide is a taboo subject in most countries. Although it is being increasingly investigated among adolescents, there are few scientific studies on the suicide of younger children (Under 13 years of age), and there are no data on the incidence of this phenomenon at an international level. However, it is known that the reasons that lead children to commit suicide are very different from those that motivate adults.
Child suicide is sometimes difficult to diagnose, since living children have more difficulty than adults in expressing their conflicts or unhappiness. The suicide of the youngest children is also confused with or thought of as an accident: many times attributed to leaning on the windows or crossing the street at the wrong time, for example. In addition, the death of orphaned children and/or those who live on the street are not usually investigated or even registered by the authorities in some countries, which makes it difficult to have statistics or carry out studies.
