There can be no explanation when mental illness is the cause. A very good friend of mine has a history of mental illness, his daughter suffers from it also and is on medication and has been advised not to have children, and his only son committed suicide at the age of 32.
Contrary to what a few folks on this site who will show up shortly have to say about suicide and selfishness, it is a medical illness caused by a chemical imbalance in the brain.........
My prayers go out to Mr. Warren's family and every other family that has had to face the loss of a loved one due to this insidious, self destructive disease.......
There is a third possibility beside selfishness and the equally fashionable diagnosis of chemical imbalance, and that is natural response to life’s difficulties.
Thank God, another rational post and sympathy for the family!
