Holly Hagan shares emotional post to mark one year since her sister Darci died aged 19 following an 'accidental overdose' of crystal MDMA - before her heart was used in life-saving transplant

Holly Hagan has shared an emotional post marking one year since her sister Darci tragically passed away aged 19. 

Darci Rose Gibson died following a night out in Manchester in October 2025 after taking an 'accidental overdose' of crystal MDMA leading to multi-organ failure. 

Holly later revealed that following her death, Darci saved the life of a stranger by donating her heart. 

And taking to Instagram on Tuesday, Holly wrote: '1 year without you. We love and miss you so much Darci xxx.'

Reflecting on the tragedy a year ago she wrote: 'Today was the day I recorded your heartbeat on a doppler to put into a bear for my parents.. it was the day they checked to see if your heart was suitable for transplant..

'the day they searched the database to find a match.. the day they ran 2 rounds of brain activity tests whilst we watched them find no signs of life..'

She continued: 'The day I went shopping for the perfect pair of pyjamas for you to be comfy and warm in after donation.. 

'the day we took photos of all your tattoos and realised one said "everything happens for a reason" and the one that shook us all "live where your heart finds life" whilst you were about to give your heart to someone else..

'It was the day I sat on the phone to the transplant nurse at 10pm after she told me everything had gone well and your heart was on its way to the recipient.. the day I sat on my utility floor and prayed for a stranger to live whilst trying to process that you had died.'

She added: 'But it wasn't just the day you died, it was the day you saved a life.. the day you became a hero and an angel all in one.

'Not a day goes by that we don't mention you, whether it's when we see a butterfly, or AJ's wearing minions socks (she loved minions) or we're watching lion king and he asks if you're with mufasa in heaven.

'I won't let anyone forget you much baby girl!'

Holly's friends rushed to send their love in the comments as her Geordie Shore pal Sophie Kasaei penned: 'A year of having an angel protecting you and watching over you all beautiful darci/'

Chloe Ferry wrote: 'Sending love,'  

Holly's husband Jacob Blyth wrote: 'Strongest woman I know. Love you a lot.'

Back in August, Holly issued a warning to festival-goers after her sister died of an accidental drug overdose. 

She took to Instagram and wrote: 'I haven't stopped thinking about the fact that someone might not make it back from the festivals.

'When I see people's videos walking into the camp grounds so happy for the weekend's of their lives.

'I just think I hope to God you all make it home. On average 5 people a year die during UK festivals and the vast majority of those deaths are MDMA related.

'Nobody thinks it'll happen to them until it does. I know my sister's death won't be the last of this nature and it's such a gut wrenching thought that other families will have to go through what we have.

'Please be careful. Look after your friends and don't show off. It's not worth the risk.'

Holly was devastated when her sister passed away last year. At the time, she paid tribute to paramedics and staff at the MRI 'for giving my sister the absolute best chance'.

She wrote: 'It is with immeasurable grief and sadness that our baby girl, my baby sister Darci Rose passed away peacefully holding my hand surrounded by family and her best friends.

'She was never in any pain. The last four days have been something I hope no family ever has to go through. We are traumatised in every sense of the word.'

Thanking all medics involved in her care, she added: 'Because of you all we have had the opportunity to hold her hand, stroke her hair and feel her heart beating for the last time. 

'We will forever be grateful for the way you have looked after her and us throughout this unimaginable process.

'Darci is so beautiful and she genuinely didn't even realise it.'
