The Void

It comes in waves...I feel great one day, but down in the dumps the next. I can't shake it. I struggle to find my place. I love what I do, but I often feel as if something is missing...I can't put my finger on it. It saddens me but I can't shake it. I've tried several different avenues to fill the emptiness: hanging out with friends, bike rides, history documentaries, prayer, retreats, reading. I can't get this monkey off my back or fill the pit inside. Why won't the hurting stop?
