The tormented singer, 24, who only last month spent two weeks in rehab, has returned to her old habits after telling chums: “I can’t go on.”

Amy — whose husband is in jail — is taking cocaine, ecstasy, cannabis and booze to dull her emotional pain, according to friends. They shockingly revealed:

She got a reluctant pal to smuggle drugs into the London rehab clinic on her FIRST NIGHT there.

Was “clean” for less than TEN days — in her failed bid to pass a drugs test to get a US visa to attend the Grammy Awards.

FEARS that without drugs she is just a ZOMBIE.

One horrified friend told how last week Amy deliberately burnt her hand with a lighter, screaming: “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. Colours aren’t as bright, love doesn’t feel real. I don’t know who I am and I just feel numb.”

The pal added: “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 said: “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.”

The revelations follow Amy’s twitchy and erratic performance at the Brits.

Her hubby BLAKE FIELDER-CIVIL, 25, is awaiting court over trial fixing allegations.

Amy — who wears a locket with his photo — is said to have be obsessed with JOHNNY CASH’s version of the haunting Nine Inch Nails track Hurt.

The first line is: “I hurt myself today, to see if I could feel.” A pal said: “It terrifies the rest of us.”
