Doctor Alex George has reassured fans that he is "still going" after the death of his younger brother.
A week ago the 30-year-old shared the heartbreaking news that he had lost his sibling Llyr "to mental health" just weeks before he was due to start medical school.
George has gained a legion of new followers over the last few months thanks to his regular videos filmed on the coronavirus frontline, but he is now taking a step back from social media following the tragic development.
Writing on Instagram Stories on Thursday night, he said: "So many of you are checking in on me so I want to say thank you and let you know I am still going.
"In time I will be ok."
Llyr's cause of death has not been revealed.
