For Amy Winehouse, a year that started with wide acclaim and commercial success will end with yet another string of show cancellations over concerns about her mental health and bizarre behavior.

In a statement issued yesterday from her rep Tracey Miller, Winehouse said that she was canceling all remaining shows in 2007--she was set to perform throughout the UK in December--"on the instruction of her doctor."

"The rigors involved in touring and the intense emotional strain that Amy has been under in recent weeks have taken their toll," Miller said in the statement. "In the interests of her health and well-being, Amy has been ordered to take complete rest and deal with her health issues."

Winehouse, 24, has had a much-publicized battle with drink and drugs over the past six months, in addition to concerns about her overall physical and mental health. Compounding matters in recent weeks has been the incarceration of her 25-year-old husband, Blake Fielder-Civil, on charges stemming from a case in which he is accused of assaulting a barman in June.

"I can't give it my all onstage without my Blake," Winehouse said in the statement. "I'm so sorry but I don't want to do the shows halfheartedly; I love singing. My husband is everything to me and without him, it's just not the same."

Following a raid of the couple's London home earlier this month, Fielder-Civil was detained on claims that he and a group of friends attempted to bribe the allegedly assaulted barman $400,000 to change his testimony in the assault case. He will remain in custody until January 18.
