I had a friend who once said that varicose veins was proof that we were not an apex species. I would also say that depression is proof. How can something that comes into your life and removes all joy be a benefit to a population?
I could see if the depression energized a person to make changes, but it seems to do the opposite; it seems to sap energy. It seems to leave the person less able to make changes in their life than before the depression set in. Is it a means of cleaning the filter of the gene pool?
But that would not seem like a possibility, because many who have depression do go on to produce another generation. Also, depression seems to attack those who do have things that are of benefit to a society.
Why the pondering? I just had the floor fall out from underneath me, yet again. I seemed to be doing fine and then I started to contemplate my status in life and began to feel totally lost; totally backed into a corner. The vacation was nice, but instead of fortifying for continued living, it just brings the frustrations of life into sharp focus. And when I look around, all I seem to see is what life is not. I try to look toward the positive things, but these keep getting drown by the frustrations and the let downs. I really don't want to be doing this any more.
Sorry for the bummer. I hope it clears the thoughts and lets me go on.
