Sonia's life was transformed after she received a heart valve transplant at the age of 17.
She says: “When I was about 14 things started to become really noticeable. I couldn’t walk across a street or speak to someone without being breathless.
“Walking over a road would feel like a marathon.
“I was 17 when I had my heart valve transplant.
“I know it’s a cliché, but it is like having a new lease of life after transplant. You become so accustomed to being unwell and unable to do everyday activities, so being able to do all the things I loved doing before, such as tap dancing, was amazing.
I tap-danced for 12 years before my op and had to give up due to illness. I’m dancing again now and five months after my transplant I ran a 10k race!
Every day across the UK, someone dies waiting for an organ transplant.
The law around organ donation in England has changed to help more people pass on more organs to save and improve more lives like Sonia's.
You still have a choice if you want to be an organ donor when you die.
Whatever you decide, make sure you let your family and friends know.
