The 23-year-old suffered from the condition restrictive cardiomyopathy since she was 18 and had a transplant earlier this year.
She said: 'I was breathless and struggling to walk up hills. It got to the point where I couldn't walk very far on the flat. I was lethargic and, as it progressed, it started to affect my liver.'
She was glad to say a final farewell to her old unhealthy heart.

The exhibition, at the new £30million Wellcome Collection, in Central London, ran until September 16.
