blow mcqueen 2003 Was Isabella Blow's suicide a factor in Alexander McQueen's death?

Internationally acclaimed designer Alexander McQueen was found dead in his London home Thursday, Feb. 11. He had apparently committed suicide.
One LA stylist — George Blodwell — told The Dish Rag that McQueen’s mother’s recent death  was a major factor in his suicide.
But McQueen also lost another important female in his life. A stylist named Isabella Blow, credited with discovering McQueen, and being his advocate and friend in the early years of his career, killed herself in 2007 by drinking weed killer.
Fashion history has McQueen signing a lucrative deal with Gucci in 2000, a deal which was reportedly initiated by Blow. 

]]>Blow felt left out because McQueen did not take her along when he sold his brand to Gucci. “Everybody else got contracts, and she got a free dress,” says Daphne Guiness, a Blow friend.

Blow was despondent for several years. After being found on a bathroom floor by her sister, she was rushed to the hospital where she told doctors that she had drunk Paraquat, a weed killer. She died the next day.
But there were many other factors in her depression and death. She had ovarian cancer, was diagnosed as bipolar and had undergone electroshock treatments. 
She had previously tried to commit suicide with sleeping pills, by driving her car into the rear of a truck, drowning in a lake, jumping off the Hammersmith Flyover (she broke both ankles) and overdosing on a beach in India.
