According to media reports and a biography written by Winehouse's father, Traviss and Winehouse had planned to marry and intended to have children. After Winehouse's death, Pete Doherty said that he and Winehouse had been lovers at one point. However, in July 2008, when Rolling Stone reporter Claire Hoffman asked Winehouse about her relationship with Doherty, Winehouse replied: "We're just good friends", and added: "I asked Pete to do a concept EP, and he made this face, he looked at me like I'd pooed on the floor. He wouldn't do it. We're just really close". Substance abuse and mental illness Winehouse's battles with substance abuse were the subject of much media attention. In 2005, she went through a period of drinking, heavy drug use, and weight loss. People who saw her during the end of that year and early 2006 reported a rebound that coincided with the writing of Back to Black. Her family believes that the mid-2006 death of her grandmother, who was a stabilising influence, set her off into addiction. In August 2007, Winehouse cancelled a number of shows in the UK and Europe, citing exhaustion and ill health.

In various interviews, she admitted to having problems with self-harm, depression, and eating disorders. Winehouse told a magazine that the drugs were to blame for her hospitalisation and that "I really thought that it was over for me then." Soon afterwards, Winehouse's father commented that when he had made public statements regarding her problems he was using the media because it seemed the only way to get through to her. In an interview with The Album Chart Show on British television, Winehouse said she was manic depressive and not alcoholic, adding that that sounded like "an alcoholic in denial". A US reporter writes that Winehouse was a "victim of mental illness in a society that doesn't understand or respond to mental illness with great effectiveness." In December 2007, Winehouse's spokesman reported that the singer was in a physician-supervised programme and was channelling her difficulties by writing a lot of music. The British tabloid The Sun posted a video of a woman, alleged to be Winehouse, apparently smoking crack cocaine and speaking of having taken ecstasy and valium. Winehouse's father moved in with her, and Island Records, her record label,
