Singer Jessie J has said she had her "worst day so far" since her breast cancer diagnosis, saying she struggled with "panic attacks, tears, big fears, anger and overwhelm".
The British music star revealed last week that she had been diagnosed with "early breast cancer" and that she would have surgery after performing at London's Summertime Ball.
Taking to Instagram Stories at the weekend, the 37-year-old singer updated her followers, writing: "Honestly, had my worst day so far yesterday since my diagnosis and the busiest three months I have had in years. Work. Toddler. Cancer. Life etc had my mind [drained].
"Panic attacks / tears / big fears/ anger / overwhelm. Bad. And you know what helped?
"I ate a corn on the cob. Turns out it's extremely hard to panic or cry while eating one. Highly recommend. Instead (sic) mood shift."

She added: "Tomorrow is a new day. The [rollercoaster] of cancer is [draining]. I won't be just talking about the highlights. And making jokes all the time. That isn't real life. Goodnight."
Returning to Instagram on Monday, the singer shared some more thoughts, writing: "IMO [in my opinion]. It's [key] to acknowledge fear anger sadness panic overwhelm and let it come up and come out.
"Holding it in won't make it go away. In any challenging situation in life.
"So when I posted what I did yesterday about my current challenge in life, also while making light of the situation.
"That was one day in 10 weeks that I just lost it and was completely drowned in all the negative and bed feelings any cancer journey can bring. Which is healthy and needed."
"I say this because I have had a lot of people since I posted that say to me things like 'Don't think about the negative' and 'To beat this you have to stay strong', 'Good thoughts only', and don't get me wrong I know all are meant with well intention and love.
"But it's sparked me thinking about how interesting it is in what we individually see as being strong is. I have always advocated for being real. Honest in your feelings. We cannot heal what we don't acknowledge."
She continued: "So I will cry, I will be scared, I will panic, I will feel all of it for a minute or even a full day.
"And then eat a [corn on the cob] or listen to a song that lifts me up or laugh with a friend. And then go and be a mum, and go to work and show up and be what I feel 90% of the time.
"Strong, fearless, healthy, and make some jokes about it all because that's my way. But I will not ignore the 10% that is fear and the sadness."
