I thought it was "trendy" because a number of celebrities have done it recently. A friend told me about the Werther effect which says the behaviors can be contagious and that is especially true with suicide.
A kid at a local school killed herself two days ago. Apparently the teachers don't get any training to recognize the signs of a kid contemplating this. After one of my students who I cared about in Japan attempted suicide, I realized that sometimes the signs are not so clear or your too damn busy to recognize them. Thankfully she survived.
I asked my school if they could provide the teachers training in this area. They seem to be enthusiastic about the idea and a teacher already recommended a counselor who could provide the training. Hopefully it will happen soon.
