Some ppl say that reason for suicide is not beeing able to become German no1 keeper, and "irony" is that Joakim Lew ( I think he was manager when that **** happened) was going to make him no1....
Enke sadly killed himself because of the loss of his daughter. He couldn't cope with it and it eventually consumed him to the point of doing what he did. Feel sorry for his wife though, losing her family like that.
