There is another way that these terrible feelings can occur. And it is not brought on by choice, and cannot be turned off by choice. It is because of the chemistry within our bodies. There are many names given, and so common that it is compared to the common cold. Depression.
When chemical changes occur, all the will power and desire we might muster, will not change the emotions we feel. Ask any women, who has had hormonal changes occur, if she can shut them off at will. Or control them in any way.
Abraham Lincoln, who struggled with depression throughout much of his life, once wrote, "If what I feel were equally distributed to the whole human family, there would not be one cheerful face on earth.”
