These deaths are tragic, and sometimes there are other forces at play.
My friend Andy Ettelson took his own life; his girlfriend had recently broken up with him. Those who didn't know him might assume that his suicide was due to heartbreak, but those close to him knew that his 25-year struggle with his bipolar condition was the more likely culprit. He refused to stay on his meds.
When a mutual friend called me to let me know that Andy was dead, he said, "you may wonder why I sound so emotionless. Let me tell you why: I had been expecting the call for years, so when Andy's father called me, I knew right away what happened."
