The suicide of a child may be the worst thing that could happen to any parent. Karen Letofsky has worked for decades to help prevent suicide via methods ranging from counseling, to training, to fundraising, to putting nets on bridges in her home town of Toronto. She shares her hard gained knowledge with us today in hopes that it can help us spot - and act on - early signs to get our kids the help they need now instead of wishing we had when they needed it.
