Getting old. Over time... Family dies or moves away. Friends die or move away. You become less active. You make less new friends... so your base of friends shrinks more and more. Everyone is busy with their lives... so every body becomes more distant and contact becomes more infrequent. You become less social. Your life becomes a bit more withdrawn. A bit more isolated. Memories start to fade away. Your life seems to fade away. More & more you feel that you, your life, your existence, is fading away. This feeling slips in and out particularly prevalent when quiet times start to pike up. A bit concerning as it happens more often. I guess it's just part of life.
