Doctor Alex George has shared a moving tribute to his younger brother Llyr on social media one year on from his death.
The 19-year-old tragically took his own life last summer, just weeks before he was due to begin medical school.
Alex has since gone on to become a staunch advocate for education of mental health issues among younger age groups and in February was appointed by Boris Johnson as the government's Youth Mental Health Ambassador.
Posting a picture of him with Llyr and his parents on Instagram this morning, Alex wrote: "I can't believe it's been a year. Some days I really can't accept or understand that you are not here. We miss you so much Llŷr.
