Rhiannon was diagnosed with Ulcerative Colitis shortly before her 17th birthday, when she was studying A-levels at college.
It took her an extra year to complete her A-levels but Rhiannon remained determined to go to university.
In one of five films created about young people living with Crohn's and Colitis, she shares her experience of studying at university.
Her lecturers must have been impressed because despite periods of ill health - including a hospital stay that caused Rhiannon to miss two months of university - she graduated with a first-class honours degree last summer!
Our young person films project received £17,000 of funding from players of the People’s Postcode Lottery through People’s Postcode Trust.
