Michael Bryan, a fashion-school student, died Feb. 26 after leaping from the balcony of his eighth-floor apartment.
People.com quoted the coroner's office as saying in a report it released Wednesday Bryan left a note that "outlined his unhappiness with his life and his intent to kill himself."
The report also said Bryan had been depressed because of "bad school grades and a visit from a former girlfriend," People.com said.
Bryan was one of Osmond's eight children.
