Amy Winehouse is back on drugs

Troubled Amy Winehouse is back on drugs – leaving those close to her fearing she is on the brink of an emotional breakdown.

The ‘Rehab’ star, 24 – who spent the majority of last month in rehab, has returned to her old habits, after telling shocked friends: “I can’t go on.”

The singer – whose husband Blake Fielder-Civil is currently locked up in a London prison – is, according to friends, taking cocaine, ecstasy, cannabis and booze to dull her emotional pain.

The friends claim that Amy – who bagged an impressive five Grammys at the prestigious awards ceremony earlier this month, ordered a reluctant pal to smuggle drugs into the private London rehab clinic she had checked into on her first night there – and she only managed to stay clean for less than ten days.

The friends also fear that Amy – who is frightened that without drugs she is just a zombie – could seriously harm herself after she deliberately burnt her hand with a lighter last week, while screeching: “My life is a shell of what it was.

“People talk to me and I just zone out. It’s like the whole world is now stillborn. colors aren’t as bright, love doesn’t feel real. I don’t know who I am and I just feel numb.”

The pal added to British newspaper The Sun: “We were sat around the table when she held a lighter over her hand and let the flame scar her skin.

“Amy has been up and down in a way she never was before. One minute she’ll be fine, the next she’ll be in a heap on the floor, screaming she can’t go on. She feels that rehab is turning her into some sort of zombie with no emotion.”

Another friend added: “On the first night in rehab she begged a friend to take her in some drugs.

“After that she did not take anything for a week to ten days. But that was just about trying to get her to the Grammys. Now we’re back to the dangerous levels of before.”
