Just Listen--how we cannot know another's internal life, no matter how well we know them

My brother did not commit suicide.  He did contemplate it.  

I want to share with you the number for the Suicide Prevention Hotline in the U.S. It is 800-273-8255. 

There are international numbers/resources also available, and can be easily found through an online search.   www.opencounseling.com is one place to find them.
