Troubled singer Amy Winehouse insists her problems with drugs and alcohol stem from "boredom" and feeling like she has "nothing to live for".
In a rare interview with Rolling Stone magazine, the 'Back To Black' hitmaker reveals that after her husband Blake Fielder-Civil was jailed on charges of assault and perverting the course of justice in November 2007, she felt like her life wasn't worth living.
The Grammy award-winning singer subsequently cancelled her UK tour and ended up in rehab in an attempt to kick her addictions.
She was also treated at a London hospital for traces of emphysema last week.
Winehouse blames her downward spiral into drink and drugs on her current unhappy state.
She says: "To be honest, my husband's away, I'm bored, I'm young. I felt like there was nothing to live for. It's just been a low ebb."
However, the star insists that although she was treated at a London clinic in March, she doesn't feel like she has fully completed a rehab programme.
She adds: "I've never been to rehab, I mean, done it properly. I'm young, and I'm in love, and I get my nuts off sometimes. But it's never been like, 'Amy, get your life together.'"
