Nathan Abbott, 22, from West Sussex was bullied mercilessly at school, so badly that he chose to leave.
But since then, Nathan has raised £30,000 for charity, has been nominated for a Pride of Britain award and has founded a charitable fundraising movement called 'Freestyle 4 Smile', which is aimed at raising funds and awareness for Smile Train.
Nathan was born with a bilateral cleft lip and palate and he would be bullied mentally and physically for it.
But he decided the bullies weren't going to beat him.
He decided to take up long distance swimming and started fundraising for cleft palate charities.
Children who have received surgery through his efforts have sent pictures to say thank you.
But Nathan worries that with modern technology and social media, it is harder to escape the bullies.
Nathan has suffered dozens of painful surgeries on his nose and mouth over the years.
But it was the bullying that caused him most pain.
Next year, Nathan will be undertaking a 60 mile swim around the Isle of Wight, with a target of completed 20 miles a day for a consecutive three days.
The challenge will take place soon after one of his last operations and it will also mark the final year of his surgery journey.
