A teenager who may not live to see her 21st birthday has taken to YouTube in a bid to find an organ donor who could save her life.
Cystic fibrosis sufferer Holly Pereira, 19, urgently needs two lungs and has filmed a heart-wrenching three-minute black and white video highlighting her plea.
She says: “There is nothing more I can do but hope that call will come. But sadly I know sometimes it’s too late and the call won’t come on time.”

The pretty teen, from Pound Green in Buxted, East Sussex, reveals in the clip how she finds everyday tasks like walking very difficult and was forced to quit university because of her poor health.
Holly was born with the condition – which causes mucus to build up and clog the lungs – and was put on a transplant waiting list three months ago.
And with only 20 per cent of her lungs now functioning, she is now in desperate need of a double lung transplant.
She says: “I live with cystic fibrosis, a condition that affects the lungs and the digestive system.

“It makes the smallest, everyday tasks, like showering, walking or taking the stairs very difficult as I get out of breath very easily.
“Being put on the list means that my chances of survival wihout a transplant may mean I only have a few years left to live.
“Due to the lack of organs available I may find it hard to find a suibtale donor. I am very small and my blood type that I am means I may have a longer wait.
“This could be 18 months or over and during this time my illness may get progressively worse, which means I may rely on oxygen to breathe and may not be able to get around properly.
“To be able to receive a new pair of lungs would mean that my life would be significantly better, I would be able to do things I can’t do at the moment.”
She ends the video by urging people to sign up to the organ donor register and saying how, once she does not need them, she will give “any of my healthy organs away”.
Miss Pereira’s brother Jake, 18, also has the condition and may need the same procedure.
Their father, 50-year-old private plastic surgeon John Pereira, who works at The Esperance Hospital in Eastbourne, said: “We didn’t know Holly had the condition until Jack was born.
“It was a double whammy.”
Miss Pereira adds in the film: “If I can get just a few people to sign up to the register which in future saves lives, even if its too late for me, that would be amazing.”
Holly, you are a very courageous young woman – I am sure your family are very proud of you!
Inspired by your story, I have signed up for organ donation, as have my two teenage daughters. I have posted on my Facebook page urging family and friends to sign up for organ donation and I only hope that one or two more do so.
I hope you get the donation I know you desperately need.
Best wishes.
