She wrote a goodbye message on Facebook, just hours before she died.
“I love you all but have decided to go be an angel and watch over my beautiful loved ones instead,” she wrote.
“My life would have been so hard even with new lungs in the state I'm in now so bye everyone.”
Miss Bridges was the founder of Couture Make Up Bar in her home town of Tredegar, South Wales, in 2013, according to the Mirror.
She had suffered from cystic fibrosis since she was three months old – a disease that affects the lungs and digestive system, which results in difficulty breathing and coughing up mucus. The doctors said the lung transplant was unlikely to work due to the high levels of antibodies in her system.
Miss Bridges wrote earlier on Facebook that she was suffering immensely in hospital.
“I'm dying - life's hard enough even if I was in a 5 star hotel life would be miserable,” she wrote.
Her mother, Jacqueline Gold, told The Daily Mail: “I never thought she'd live long enough to make it to school, but she was fighter.
“She made it to 28 years old. But I've been waiting to bury her since she was just three months old - I'm so grateful for the time we had."
