Jessie J revealed she suffered her ‘worst day so far’ amid her breast cancer battle as she broke down in tears and struggled through panic attacks on Saturday.

The singer, 37,  who announced her diagnosis in an emotional Instagram video last week, admitted ‘drowning in the negativity’ of her situation as she took to her Stories with a latest health update.

In a lengthy post on Sunday, she wrote: ‘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].

Jessie, who shares two-year-old son Sky with partner Chanan Colman, continued: ‘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 mood shift’.

Jessie J, 37,  revealed she suffered her ‘worst day so far’ amid her breast cancer battle on as she broke down in tears and struggled through panic attacks on Sunday.

The singer who announced her diagnosis in an emotional video last week, admitted ‘drowning in the negativity’ of her situation as she took to her Stories with a latest health update 

‘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 social media on Monday, The Price Tag hitmaker penned: ‘IMO. 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. 

She went on: ‘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] or listen to a song that lifts me up or laugh with a friend on Face Time. 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 sadness’.

It comes after Jessie appeared to drop a hint about her cancer diagnosis weeks ago during a performance in London.

But the announcement appears all the more poignant now given what Jessie is reported to have told fans while performing at Union Chapel on May 20.

Accorrding to The Mirror, the star told her fans at the show she was putting herself first and wanted to have fun. 

She said: ‘I know we are all going through our own battles in life, we are all struggling in our own way. We talk about it sometimes, and sometimes we don’t.

She wrote: ‘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]

She hit back at those who told her ‘not to think about the negative’

She then shared a cheeky throwback snap of herself in the bath quipping that her ‘little boobs’ had been so rude and adventurous  

‘I’m grateful I have the voice and the strength to be able to put those experiences into songs that people can take and make them their own soundtrack to help them get through a tough time, a good time, a scary time.’

The hitmaker also seemed to reference her cancer battle when she introduced her new song No Secrets.

‘This song for me, more so than ever right now, is getting me through my life,’ she said.

Jessie revealed that she discovered she had the illness before the release of her hit new single No Secrets, which was released on April 25.

The mother of one said she would be undergoing surgery after performing at the Summertime Ball in London on June 15.

In the clip, Jessie said: ‘Hi, I have been going back and forth a little bit on whether to share it. I want to but there’s lots of opinions outside…

‘Also knowing that I want to share with my fans and the people that care about me, also I’m a sharer. I’ve always shared everything that I go through in my life.

‘Before No Secrets came out, I was diagnosed with early breast cancer. Cancer sucks in any form but I’m holding onto the word early.

‘I have been in and out of tests throughout this whole period, adding that she had not been adequately ‘processing it because I’m working so hard.’ 

Jessie said she ‘wanted to be open and share it – one, because selfishly I do not talk about it enough. I’m not processing it ’cause I’m working so hard.’

It comes after Jessie appeared to drop a hint about her cancer diagnosis weeks ago during a performance in London 

Her recent announcement appears all the more poignant now given what Jessie is reported to have told fans while performing at Union Chapel on May 20

She added: ‘I also know how much sharing in the past has helped me, with other people giving me their love and support and also their own stories.’

The London native stated: ‘I’m an open book. It breaks my heart that so many people are going through so much, similar and worse. That’s the bit that kills me.’

‘I just wanted to let you guys know it wasn’t something I planned. I’m getting to keep my nipples. That’s good, it’s a weird topic and a weird situation.’

Jessie reflected: ‘To get diagnosed with this as I’m putting out a song called No Secrets, right before a song called Living My Best Life – which was all pre-planned, before I found out about this. I mean, you can’t make it up.’ 

She joked: ‘It’s a very dramatic way to get a boob job,’ adding that the operation to excise the cancer would occur sometime after her appearance at Summertime Ball at London’s Wembley Stadium on June 15.

Jessie told fans she would ‘disappear for a bit after Summertime Ball to have my surgery and I will come back with mᴀssive t**s and more music.’

Continuing the lighthearted mood, she wrote in the caption: ‘No (more) Secrets and is it too soon to do a remix called Living My Breast Life?

‘All jokes aside (you know it’s one of the ways I get through hard times). This last two months have been so amazing, and having this go on alongside it on the sideline’s has given me the most incredible perspective.

‘BUT… your girl needs a hug. Also not getting mᴀssive t**s. Or am I? No no.. I must stop joking?’
