Amy Winehouse's dad collapsed after the strain of looking after his troubled daughter took its toll.
Mitch Winehouse dedicated himself to looking after Amy two weeks ago, after she discharged herself from hospital where she was being treated for lung problems, but the stress of being her full-time carer triggered panic attacks.
Mitch revealed: "I am awaiting the results of tests. I'm going away for a few days and we will see what happens after that."
A friend of taxi driver Mitch told Britain's The Sun newspaper: "He isn't well. He has been taking a lot on and has been dedicating himself to trying to improve Amy's health. But his own health has suffered as a result. He has been having stress-related panic attacks and collapsed at home last week."
Amy was diagnosed with the early symptoms of lung condition emphysema when she was hospitalised last month. Mitch has attempted to curb her wild partying - in particular her smoking and drug taking - even making a televised plea to her friends to stop giving her drugs and cigarettes. He insists even one cigarette was putting his daughter's already damaged lungs in serious danger.
Amy ignored her father's advice during her performance at Scotland's T in the Park festival yesterday (13.07.08) by smoking onstage.
The 24-year-old singer dedicated her song 'Some Unholy War' to her husband Blake Fielder-Civil, who is currently in London's Pentonville Prison awaiting sentencing for to pervert the course of justice and grievous bodily harm (GBH).
