Amy Winehouse predicted she would die at the age of 27.
The 'Rehab' singer - who passed away at her home in Camden, north London, on Saturday (23.07.11) - believed she would become one of a number of music stars in the '27 Club', which includes Jimi Hendrix, Doors singer Jim Morrison, Nirvana frontman Kurt Cobain and Janis Joplin, and pass away at that young age.
She also had an "obsessive" personality when it came to drugs, alcohol and food.
Her friend Alex Foden, who once lived with the musician, said: "Unfortunately, Amy had a very obsessive personality. She did everything to extremes, especially when it came to food and drugs. She loved food.
"But she'd either have binges - eating loads before running up to the toilet and getting rid of it all again - or she'd go up to four or five days without eating, surviving on alcohol, drugs and sweets.
"Amy always told me she thought she would die young and that she knew she'd become part of the '27 Club'."
Alex claims her problem with drugs became so prevalent she would sometimes get through £1,000 worth of cocaine in one night, because she would be paying for all her friends to get high as well.
Mitch Winehouse had desperately tried to get his daughter into the same rehab clinic which helped Russell Brand shortly before her death, it has emerged.
Chip Somers, the head of a rehabilitation centre, said he had been in regular contact with Mitch Winehouse before the 27-year-old singer was found dead in her north London home on Saturday afternoon.
Mr Somers, who founded Focus 12, said: "Her father came here for the day to find out what we were like and he really liked what he saw."
Mr Winehouse urged his sick daughter to go back into rehab.
But Chip said: "She turned down that offer. She had turned down many other offers of help."
Mr Winehouse fought relentlessly in a bid to help Amy beat her tragic addiction.
Chip, who has worked with TV star Davina McCall and comedian Brand, said the tragedy was being replayed in families up and down the country.
"It shows you cannot protect yourself from the consequences of extreme drug use.
"Anybody, if they abuse drugs or alcohol, then no amount of money will protect you from that.
"Unfortunately, money often protects you from the consequences of drug use. It can help buy people out of trouble," he said.
"People at her financial end of the spectrum often take much longer to realise they have a problem.
"Addiction affects people irrespective of wealth, power or position.
"The death of any addict is very sad.
"But this story is being re-enacted in three or four homes in the UK today and again tomorrow and the next day.
"This is happening all over the country."
In a tribute to Winehouse, Russell Brand said that without the help of Mr Somers and Focus 12 he may also have been killed by addiction.
The actor and comedian wrote on his website: "I was 27 years old when, through the friendship and help of Chip Somers of the treatment centre Focus 12, I found recovery.
"Through Focus I was introduced to support fellowships for alcoholics and drug addicts which are very easy to find and open to anybody with a desire to stop drinking and without which I would not be alive."
The singer's death has sparked a clamour for her albums.
Music store HMV in Ipswich reported a staggering 800 per cent rise in sales of her two albums since the singer was found dead.
