Russian Vogue cover girl Ruslana Korshunova who committed suicide by diving from her Manhattan apartment, on the ninth floor, Saturday, felt confused about the direction of her life and struggled with a stomach disorder in the days prior to her death.

The 20-year-old Kazakhstan native model, had lost a lot of weight in the last month and had difficulties keeping a balance between her personal life and her effortful work schedule, said Artem Perchenok, her 24 year-old ex-boyfriend.

"I think she just gave up," said Perchenok, who was with Korshunova on the night of the tragedy. Police found no signs of a struggle. Moreover, friends said she had not been acting suicidal. On Sunday, authorities officially declared Korshunova's death a suicide.

New Yorker Mark Kaminsky, 32, the super model’s latest boyfriend, pointed out insistently her “liking what she did.”

One investigator told the New York Post they found several bottles of medication having the labels in Russian. Korshunova left no note before she jumped. She was four days away from her 21st birthday.

Her mother in Kazakhstan said the suicide was "completely unexpected."

"She's had her ups and downs but never anything that would lead to suicide," she told the Post.

But her death — after spending the night watching the movie "Ghost" with her ex — was completely unanticipated.

"I never heard of her being depressed. Maybe a year ago, when she wanted to change agencies," the mother told the Post. "But she would explain her problems. I can't understand why she wouldn't explain her problems [now]."

Korshunova wrote months before in her online journal that she felt "lost" in America.

"Will I ever find myself?" she added in March on her page on a Russian social networking site. Korshunova felt she was over the hill in a domain that is constantly searching for a brand new face, her ex said.

The Russian Rapunzel, as she was nicknamed because of her flowing, Rapunzel-like tresses, modeled in commercial ads and campaigns for Paul Smith, Moschino, Christian Dior, Marc Jacobs, DKNY and Vera Wang. She also made the cover of French Elle and paraded the catwalk for designers like Jill Stuart and Betsey Johnson.

Korshunova found fame after a model booker noticed her in the article of an in-flight magazine about the German club in her home town of Almaty. “I saw her by chance and she looked like something out of a fairytale. We had to find her and we searched high and low until we did,” Debbie Jones, a senior booker at Models 1, told British Vogue three years ago. “She's really incredible, with feline features and timeless beauty.” The ravishing Kazakh, then 17, was acclaimed as “fashion's muse of the moment” by “The Sunday Times”, and British Vogue called her “a face to be excited about”.
