Irish singer Sinead O'Connor reached out to fans when she revealed her 'paralysing agoraphobia' has stopped her being able to buy food.
The singer, 53, uses two Twitter accounts, one managing her professional business with an official blue tick and another under her Islamic moniker Shuhanda Sadaqat, which she used to make the heartbreaking announcement.
After making the plea on Wednesday, the following afternoon she returned to the microblogging site to assure fans and followers: 'All good now : ) found meal delivery service : ) Am replete and happy : )'.
Sinead's mental health issues have been well documented over the years and she often uses social media as a sounding board for her woes.
Her latest messages addressed the troubles she is facing in lockdown and living in a remote area of Ireland, where she is not in a catchment area for deliveries.
She penned: 'Ok here goes a reach out. I've been secretly living with a physically paralysing, trauma related case of acute low self-esteem for the last few years and months and weeks and am lately not eating...
'[It's] because it's made me so agoraphobic I can't go to the shops. And I'm starving. I currently live in a very remote part of the country so take outs, and or grocery deliveries are not an option...
'That's why i Have clearly asked ONLY if anyone knows of meal services for people with mental health conditions who's ability to self-care is diminished. I'd eat the f**kin' leg of the Lamb of God."
She later assured fans that she was fine, however sparked concern in the interim.
Last month, Sinead appeared on The Ryan Tubridy Show on RTÉ Radio 1 and detailed her decision to train to be a healthcare assistant.
Of her reasoning, she explained: 'That's something that I wanted to do for years, it's not because of the Covid thing, it's not that I'm rushing to the frontline.
'The area that I want to work in ultimately is palliative care. The 28th of September, that's it, head down, it's just one year...that's how I'm making use of the time. I had a whole year of shows booked... That's how I'm making use of the fact that I'm unemployed for the year.'
Sinead added that being a healthcare assistant was something she's wanted to 'do since [she] was a child' as she expressed her interest in going into palliative care.
'A huge impetus for me was one of my best friends in the world actually died about five years ago.
'He asked me one night would I sleep in the bed with him when he found out he was dying and I told him I would but in the end, I was too frightened and I didn't.
'I felt from then I would never leave a person alone and I let my friend down very badly. I didn't get into the bed with him because I was so frightened...of death and dying and of him dying.'
