Dr Alex George has opened up about his grief following the sudden and tragic death of his younger brother Llŷr.
Alex, 30, recently told that he'd "lost [his] beautiful little brother to mental health."
Llŷr - 10 years Alex's junior - was due to start medical school in the near future as he followed in the footsteps of his big brother.
Alex reached out to fans earlier today to thank them for their support.
"These are the hardest times I could ever have imagined," he wrote on his Instagram Stories.
"The kindness and love our family has received has been incredible and I am so grateful.
"In the darkest times we must pick ourselves up, find strength and be there for our family and friends.
"That is exactly what I'll do."
In a heartbreaking post last week, Alex announced the news of his brother's death.
Sharing a photograph of the two of them, he wrote: "I can't believe I am actually writing this post.
"I have lost my beautiful little brother to mental health. I love you so much Llŷr.
"The kindest and most caring soul. I was so proud of you starting medical school next month, you would have been the most incredible doctor.
"We are hurting so bad. No words can explain. As a family we are devastated. We love you and miss you so much. Please rest in peace x Our boy."
The circumstances of Llŷr's death are not yet known.
Alex's Love Island co-stars have since been reaching out to him en masse.
This Morning's Ruth Langsford - who's sister took her own life in June last year - reached out to Alex in a touching post.
"Alex I am so, so sorry for your tragic loss," Ruth wrote, "I lost my sister to mental health last year so I understand the pain and shock you and your family will be feeling.
"I send you the hugest of hugs and if you ever need to talk you know how to reach me.
"My condolences to you and your family and may your darling brother rest in peace."
