The family of Barnstaple teenager Katie Gammon has announced details of her funeral. A service will take place at Barnstaple Parish Church, off the High Street, on Monday, September 7 at 12noon. Her burial will then take place at the Bear Street cemetery. Details about the wake are still being finalised but a statement released by the family today said Katie had made her own funeral plans and had asked everyone to wear purple. Katie wanted a good party; she wanted everyone she loved or knew to be there, it said. We know how popular Katie was so our only request we have is for family flowers only. However, if you wish to make a donation that would be lovely and money raised will be split between Caroline Thorpe childrens ward and the Little Bridge House childrens hospice. Katie, who underwent a double lung transplant in August 2013, died on Sunday just days after her 17th birthday. Infection She fought a lengthy battle with cystic fibrosis but had spent the last couple of months in hospital suffering with lung rejection. She was told by doctors in London on Thursday her birthday that they were unable to treat a subsequent infection. She died in North Devon District Hospital, in Barnstaple, on Sunday. Speaking to the Gazette, mum Angie Hart, said: Katie managed to open her presents in the morning and the doctors told us the news that afternoon. Safe When we got to Barnstaple, the hospital had decorated a room for her with bunting and fairy lights and when Katie got into bed she said she felt so safe, said Angie. She passed away peacefully with her family by her side. The hospital has been amazing, I cant praise them enough. Katies new lungs meant she was able to enjoy many of the things teenagers take for granted, such as going to music festivals, attending her school prom and driving a car. The former Petroc and Park Community School student was also able to sit her GCSE English exam, although she was too poorly to learn shed passed with a grade B. Life changing On the anniversary of her transplant, she wrote: Two years ago today my life changed for ever, thinking of my donor and family more than ever today. Katie spent the last few years campaigning to raise money and awareness of cystic fibrosis and organ donation charities. She helped organise a series of sponsored walks along the Tarka Trail and documented her own transplant journey on her blog entitled Everything Happens For A Reason. Precious girl She was amazing our precious girl; life is going to be so different, said mum Angie Hart. Katie was a typical teenager, very bossy. She made the plans for her funeral herself and has asked everyone to wear purple and she wants everyone to have a big party. Katies journey The Gazette has followed Katies journey over the years, as she battled to fundraise for charity, to the moment she got the call telling her that her new lungs were ready. We told how she enjoyed a normal childhood despite her cystic fibrosis diagnosis, but in 2010 her health began to deteriorate and in 2012 she was put on the transplant waiting list. In August 2013 Katie got the call she had been waiting for, and was rushed to Great Ormond Street Hospital in London for the 20 hour operation. A special memorial event is being held tomorrow (Thursday) to remember Katie. Friends are planning to come together to meet on the Tarka Trail by the civic centre to release balloons and lanterns in her memory at 7pm.
