Fashion designer Kate Spade left behind a tragic note telling her teenage daughter\u00a0 not to blame herself for her suicide.\r\nSpade, 55, was found hanged at her\u00a0Park Avenue home\u00a0on Tuesday morning.\r\nNext to her body, was\u00a0a heartbreaking suicide note addressed to her 13-year-old daughter Frances 'Bea' Beatrix, her only child, telling her she'd always loved her and not to feel guilty over her mother's death.\r\nThe note read, according to\u00a0TMZ: 'Bea - I have always loved you. This is not your fault. Ask Daddy!'\u00a0\r\nKate's husband was at the apartment when his wife took her own life according to police.\r\nThe housekeeper who discovered Spade's body reportedly\u00a0ran downstairs to inform the building's superintendent who rushed back to the apartment, cut the scarf around her neck and attempted CPR.\r\nSpade was declared\u00a0dead at the scene.\u00a0It's not clear how long she had been dead. The medical examiner will perform an autopsy.\r\nIn a statement, Spade's family reportedly said they were 'devastated by today's tragedy.'\r\n'We loved Kate dearly and will miss her terribly,' they said. 'We would ask that our privacy be respected as we grieve during this very difficult time.'\r\nA source close to the family described the moment Andy Spade picked up their daughter from school\u00a0\r\n'Everyone was crying,' a source told\u00a0People.\u00a0\r\nThe NYPD Chief of Detectives Dermot Shea said that police are not treating Spade's death as suspicious.\r\n'At this point, there was a note left. The contents of that note, as well as the physical state of the apartment and the comments of the witness, lend to the credibility that it is an apparent suicide,' he said.\r\nRelatives say her death comes after a long battle with mental illness.\u00a0Her sister\u00a0Reta Saffo told the DailyMail.com that she believes Spade had bipolar disorder which was made worse by her celebrity status after her brand took off.\r\nHowever, a\u00a0source told People that 'Kate and Andy were having relationship problems' and that he had been shopping for a new one or two-bedroom apartment in Manhattan, although other sources say they were working closely together on her new brand Frances\u00a0Valentine, a line of luxury handbags and shoes.\r\nKate and Andy married in 1994, one year after launching Kate Spade New York together.\u00a0\r\nThree years in the couple was able to open their first store, and for the next decade continue to grow the company. Kate\u00a0had launched international and home lines by 2004, having by that point sold off most of her company.\u00a0\r\nNeiman Marcus purchased 56 per cent of the company in 1999 and the remaining 44 percent by 2006, at which time Kate left the business to raise her daughter.\r\nShe told People at the time that she wanted to focus on her family.\u00a0\u00a0\u00a0\r\n'When the two of us sold the company with our other two partners to Neiman Marcus, it was kind of a time for us to take a break. So we sold Kate Spade and I personally, I don't know about Andy, I took off a good nine years raising my daughter and absolutely adored every moment of it.\u00a0\r\n'And then I realized she was becoming 12 and didn't want me around so much, so I thought I would get back into the business.'\r\nIn a 2016 interview with\u00a0Wall Street Journal, Kate spoke about how even through she had returned to the world of fashion her daughter was still her priority.\u00a0\u00a0\u00a0\r\n'I kind of thought taking that time off was unbelievably amazing,' she said of her decade-long absence .\u00a0\r\n'I thought it was, like, a gift. I really did.'\r\nOnce back at work, it was including her only child that made work a delight for Kate, and she described her excitement at getting to go to the studio with Frances on the weekends.\u00a0\r\nKate is the third major designer to take her life in the past decade, with L'Wren Scott committing suicide in 2014 and Alexander McQueen also ending his life in 2010.
