In your question you ask whether society puts too much pressure on young kids or whether it is peer pressure that drives some of them to suicide.
The most straight-forward answer seems to be a rise in mental health problems. Only today we hear of a report that claims 1 in 10 children has a mental health issue that will affect them in their lives. In some cases, without specific help, this will inevitably lead to suicide.
I believe that people who commit suicide, and I have known a few � although I�d like to think that was not a factor � are taking that last step towards a decision that they are already capable of. Some people can and some people can�t, however some people are driven to it through enforced circumstances such as a breakdown, abuse or bullying, and this identifies a sense of helplessness, not necessarily pressure. Mental health issues which drive someone to suicide is of course a sorry state of affairs, but so is the aftermath and the feelings, faux culpability and sense of compunction that close friends and relatives are left to deal with.
