The day my Sprite Dog died I walked fifteen miles. I jogged in place for 4 hours. I didn't eat. I had failed in keeping my 15 year old dog alive and the price must be paid.The only way to handle the out of control pain and guilt was with Anie. She never died on me. Her purgatory of exhaustion was far better than being lost in helplessness.I would exercise and starve until I saw black spots before my eyes.
