Mitch Winehouse revealed that his late daughter, Amy, had defied doctors' expectations and had given up drugs completely before her tragic death on July 23. 

Speaking at the superstar's funeral yesterday, July 26, Mitch explained that she had been making a "fantastic recovery". 

"Three years ago, Amy conquered her drug dependency, the doctors said it was impossible but she really did it. She was trying hard to deal with her drinking and had just completed three weeks of abstinence"

He added, "she said, 'Dad I've had enough, I can't stand the look on your and the family's faces anymore."

Mitch also opened up about Amy's relationship with Reg Traviss and admitted she was "the happiest" he had seen her in years:

"I will talk a lot about her fantastic recovery. Recently Amy found love with Reg. He helped her with her problems and Amy was looking forward to their future together. She was the happiest she has been for years."

His frank speech made sure that mourners knew she was at a peak in both her health and mental state, and he concluded, "but knowing she wasn't depressed, knowing she passed away, knowing she passed away happy, it makes us all feel better."
