Living a poor life with a rich tongue

Startled by hope, depressed by happiness seems to shadow my faith. I step out of joy into a river of sorrow to hide the tears from the fear of despair. Speaking only to those who battle again me, running from those who care. I have no face. I see only the darkest field of the summer days! I feel no pain, only the touch of the blades of success. I hear only the mutes. Tell me again! I retain no visibility.
