When John Kirwan first delivered his message of hope to those New Zealanders suffering from depression, Dafydd Sanders was enduring his "lost years".
The victim of a political fight between two warring tae kwan do factions, Sanders had his Athens Olympic dream ripped from him. Always a quiet kid ("I was known at Ilam school [Christchurch] as the boy who never smiled"), the idea he was not in control of his sporting destiny sent Sanders, now 29, into a dark place for the best part of two years.
Sanders was "grieving" for a lost goal, but he is careful to separate that from depression itself. The depression came not from missing selection for Athens, but from the idea that he had no control over his destiny.
"When you have one goal and you miss it because somebody beats you or you weren't quite good enough, you think those four years were a waste of time. When that gets taken away from you through no fault of your own, that makes it worse.
Sanders withdrew into a "dark, colourless place", rejected friends and family and lived the life of a recluse.
