Ken, hugs to you.
Do try eating healthier, and get some exercize. Get out taking some walks. It sounds like you are sad and somewhat depressed. It could have been triggered by something that happened to make you long for a less complicated time in your life, or you could be low on vitamins. As you get older you need extra some times, cause your body doesn't absorb them so easily. If it continues after a few adjustments please see your doctor. Men don't like to think of being depressed or anything but it is so easily fixed if that is what it is. Don't hit bottom first. Your chemicals could just be alittle out of whack. Even facing later years could be sitting heavy on your mind. Take in some nature and do some thinking. Take care of yourself.
