He was such a nice person, one of the kindest professional football players I've ever seen.
He's had problems with depressions for several years, especially after his bad years at Barcelona and Istanbul.
At a press conference, his wife said he always has been afraid of being not good enough, the only thing he had in mind was football.
His condition seemed to get better during this year, when he and his wife adopted a girl, called Leila.
But in the last weeks he suffered from a viral infection and his fear, of being not good enough, returned. Everyone thought things would get better now after he participated in 2 Bundesliga matches again, the last one on last Sunday.
In his last letter he apologizes to everyone he deceived in the last days, hiding the plan of his suicide.
He has been afraid of going into stationary medication, which doctors wanted him to go into till his last days because he thought his daughter could be taken away from him if people found out how bad his condition was.
