When Donald McFarlane's daughter became the first person ever to receive a heart transplant at Yorkhill, he thought her health worries were finally over.
Donald, from Parkhead, had feared the worst when 12-year-old Michelle collapsed at her grandparents house 17 years ago.
The "bright, loving" youngster was rushed to hospital, and Yorkhill medics frantically searched for the cause of her problems.
Donald, a 57-year-old salesman, said: "We got a phone call to go there and overnight she deteriorated.
"She was in intensive care.
"They told us it was her appendix at first but then they found out it was her heart."
Just days from death, doctors discovered Michelle's heart had started failing and she desperately needed a new one to survive.
Luckily, they found a donor and immediately converted the hospital's basement into an operating theatre, performing the heart transplant there and then.
Over the next seven years, Michelle was like every other girl her age - she had friends, she went out and had a passion for theatre and drama.
The teenager even appeared as an extra in BBC documentary Tales From The Edge along with her best friend Rosie, and was studying Spanish at Langside college.
The normality, however, was short lived.

After a school trip to Barcelona at the age of 19 she began to feel unwell again, and was taken to hospital for a second time.
Dad Donald explained: "Doctors said her heart was rejecting. I just didn't think this was going to happen.
"She was doing so well.
"They said there was nothing more they could do, as another heart transplant wasn't possible.
"They decided it was up to Michelle, whether she wanted to go home or go to a hospice.
"She was admitted to the hospice and she was there for a week."
Donald and his wife Diane, Michelle's step mum, were at the hospice on the night she lost her fight for life - September 11, 2005.
"It was a Sunday night, and we went into the TV room at the hospice." said Michelle.
"I went into Michelle's room to get something and saw she had passed away.
"I couldn't believe it. I told the nurses, they said she had been waiting for me to come in all day."
"Losing a child is something you never get over"
"You never ever get over it or forget about it. You miss her all the time - Christmases, partie, her brothers' birthdays.
"She's talked about a lot, by family, colleagues and friends."
Donald and auxilliary nurse Diane are now determined to help others who may eventually suffer the same fate as Michelle.
On the date of her 21st birthday, they raised hundreds of pounds for the British Heart Foundation.
On July 14 this year, to mark what would have been Michelle's 30th birthday, they are planning to hold a fundraiser to support the Prince and Princess of Wales Hospice's Brick by Brick appeal.

The cash boost will contribute to the Evening Times-backed campaign to create a brand new purpose-built hospice in Bellahouston Park, which will bring 21st century hospice care to Glasgow.
It will help to give support to more people than the current city centre facility can accommodate.
Diane said: " The hospice were incredible. They were just unbelievable with the amount of help and support they gave us and Michelle.
" The whole family are just so grateful.
"It will be a happy day, but a sad one for us as well."
Donald added: "The hospice couldn't do enough for us, and I won't forget what they did for Michelle.
"Everyone was brilliant. I can see why they have to move from Calton place, it's not fit for their purposes now. When they move to Bellahouston Park it will be great, people can go into the gardens and everything. It will really help them.
"When you mention the word hospice, you think 'that's it' but it's not like that. It's a lovely place, relaxing and the staff are lovely.
"We just want to give something back and help someone else."
Rhona Baillie, Chief Executive for The Prince & Princess of Wales Hospice said: "We hugely appreciate the support from the McFarlane family and this is such a lovely way to commemorate their daughter Michelle by providing a lasting legacy for future patients in our new hospice at Bellahouston Park."
Donald and Diane's fundraising night in memory of Michelle will take place on July 14 at the Ship Bank pub on Saltmarket, at 7.30pm.
