Duffy has broken her social media silence to confess she's been struggling to sleep ahead of the coronavirus lockdown easing.
The post is her first in five weeks after she opened up about her traumatic kidnapping and rape ordeal.
The Mercy singer, 35, told fans she's worried about the uncertain times as the country moves into a new phase of the lockdown.
She wrote: "This evening, I can’t sleep ... I have the comfort of my bed and the health of all my family, to take shelter in, but many do not.
"Health workers face fatigue, with such uncertainty ahead, people are queuing at empty food banks and the landscape is changing...
"Tonight, some of us grieve the easing of enforced lockdown - and some of us appreciate it.
"The sense of security found in a common goal, a shared goal, is changing and could now stand to divide, which it must not, above all, in adapting to a new uncertainty."
She went on to reference her harrowing confession about being kidnapped and raped, and asked fans to share their own stories on her Instagram page.
Duffy went on: "You may or may not have read my words, recently. I found them to be liberating. And so I would sincerely like to know, how are you?...
"And so, I want to create a post where you can talk openly about how you are doing. I invite you to write here, if you would like that.
"I look forward to reading how you are, about your life, and current experiences. For you to share your stories visibly with others too, here."
It comes as the country moves into a new phase of the lockdown from today, with workers in England who cannot do their jobs from home are encouraged to return.
There are also new guidelines for unlimited exercise and day trips among others for people in England.
Back in April, Duffy - real name Aimee Anne Duffy - opened up about how she was abducted and held captive for a month after being drugged at a restaurant on her birthday.
She recalled being taken to a foreign country where she was raped in a hotel room by the perpetrator.
The star wrote: "It was my birthday, I was drugged at a restaurant, I was drugged then for four weeks and travelled to a foreign country.
The Welsh star said she was too scared to run away in case the perpetrator alerted the police and they tracked her down.
She was eventually returned home and spent years dealing with the aftermath of her ordeal.
