I'm so sorry. This is painful for all of you. If anyone tries to minimize the impact or the pain, simply walk away without saying anything to him/her.
I just did an Internet search, and here are some of my results:
National Suicide Prevention Lifeline: http://www.suicidepreventionlifeline.org/
or 1-800-273-TALK (1-800-273-8255
American Foundation for Suicide Prevention: http://www.afsp.org/
How to Help Someone Who Is Suicidal: http://www.helpguide.org/mental/suicide_prevention.htm
Outside the United States, please do a country search at Befrienders Worldwide: http://www.befrienders.org/directory
These phones and web contacts are staffed by trained volunteers who will be able to help you and your family members (and other co-workers) forward.
Best wishes to all of you.
