The claims come days after Winehouse's latest pictures came out which fuelled claims of her hopeless addiction.
The pictures showed Winehouse's youthful looks totally ruined with sunken cheeks, a skeletal frame, blotches and grey skin.
The singer, who omitted her own birthday party as she realised how badly drugs have ruined her looks, is stuck in her flat trawling the web looking for photos of her in happier times.
"It is so, so sad to see the state she's got into. Those who see her on a daily basis are at a complete loss as to what to do," the Daily Star quoted Winehouse's pal, as saying.
"She is lost and bewildered and all she lives off is fizzy drinks and sweets," the pal added.
