Children committing suicide: what rage, fear, sadness could cause this?

Our children are not bright; they might
Think they are - we once thought we
Were... we grew up and realised how
Lucky some of us, we are, to be alive
Today. If we thought ourselves bright
Then, and had somehow decided to
Take our own lives, you and I would
Not have shared this moment of
Thought; it is sad that death not
Become a terrible option due to
Terrible circumstances our children
Go through... tough their young world
Is; sad and scary when a child dies, we
Must always listen to them when they
Have concerns.
