Well Sky reported that he died of an overdose of drugs and Alcohol.
So unless his drinks were spiked, he looked as though he couldn't take the shame of losing. If that is the case, it makes it even sadder.
Had his wife been there, it probably wouldn't have happened.

I think partners should be with their sporting heroes as support in times of stress.

Its had enough being away from your family for a long period. but a darn sight worse when under stress.
