Marie Osmond: Son's Suicide Is 'Probably the Hardest Thing I've Been Through'

Nov. 11, 2010— -- It has been just eight months since Marie Osmond experienced every mother's worst nightmare: Her son, 18-year-old Michael Blosil, committed suicide.

Osmond is speaking out for the first time about the day Blosil died. Today, the entertainment icon tearfully told talk show host Oprah Winfrey about the very last conversation she had with her son.

The last time they spoke, Blosil expressed despair.

"When I heard him say to me, I have no friends, it brought back when I went through depression, because you really feel so alone," Osmond said.

"I'm not a depressed person, but I understand that place, that darkness," she said, referring to post-partum depression.

Osmond became emotional as she talked about that conversation.

"I told him, I said, 'Mike, I'm gonna be there Monday and it's gonna be OK.' But depression doesn't wait 'til Monday," she said.

It was Friday, Feb. 26, when Blosil jumped to his death from the roof of his apartment building in Los Angeles.

Blosil, a first-year student at the Fashion Institute of Design and Merchandising, had battled with substance abuse and depression following his parents' divorce in 2007.

He entered rehab after the divorce.

Speaking of her son's struggles to talk show host Larry King that year, Osmond said Blosil was "dealing with a lot. He's one of my kids. He's dealing with adoption issues, all kinds of things right now."

Blosil was one of five children adopted by the star.
