Holding a grudge is like drinking poison and waiting for the other person to die. Dr. Robert Enright's research shows forgiveness therapy significantly reduces depression and anxiety, and brain scans reveal it literally rewires how you process hurt. Billy's journey started in childhood chaos, but becoming a parent opened a door: he saw his own parents not as monsters but as overwhelmed people drowning in unhealed pain. Forgiveness freed him like cutting chains he'd dragged so long he forgot they weren't part of him. Start small. Forgive the driver who cut you off. Build the muscle for the bigger stuff.
