Understanding The Signs of Suicide

"Dear Dr. Sala," begins a letter from a very discouraged friend of Guidelines, who neither gave his full name nor an address.  Jason tells about a broken home and the heartache he has experienced as his dreams and hopes fell apart.  He says, "Many times before I left, I cried to God and begged him to save my marriage.  What happened?  Where was He?  Why didn't he knock some sense into us?"  He described his ordeal as a long valley through which he was walking and then, thinking about taking his life, asked, "How long are valleys supposed to last?  Would you address the subject of suicide?"
