After a trouble-plagued second half of the year, Amy Winehouse is canceling all her remaining live and promotional appearances on doctor's orders – saying she can't perform without her husband, Blake Fielder-Civil, at her side.
"I can't give it my all onstage without my Blake," the singer, 24, writes on her Web site
. "I'm so sorry but I don't want to do the shows half-heartedly; I love singing. My husband is everything to me and without him it's just not the same."
Fielder-Civil, 25, was recently jailed
after allegedly trying to manipulate a witness in his trial on assault charges stemming from a 2006 altercation.
Winehouse's decision comes "on the instruction of her doctor," reads a statement from her label. It goes on: "The rigours involved in touring and the intense emotional strain that Amy has been under in recent weeks have taken their toll. In the interests of her health and well-being, Amy has been ordered to take complete rest and deal with her health issues."
Refunds for the remaining dates will be issued from the point of purchase, according to her label.
Earlier this month in England, at her first show since her husband's arrest, Winehouse delivered a shaky performance
, was booed and then stormed off the stage.
The cancellations cap a turbulent year for the singer. She married Fielder-Civil in May
but then struggled through a series of health and substance-abuse issues.
In August, she was hospitalized
and treated for exhaustion, canceled
a number of tour dates, then checked into a retreat
with her husband.
In October, she was arrested in Norway on a charge of marijuana possession, paid a fine but then appealed it
, saying she had not understood the charges.
