Sophie was 12 when she was diagnosed and says: “I was lucky. I had very mild symptoms. My GP was diabetic and she spotted the symptoms.”
Despite her symptoms being relatively mild, she was sent to hospital.
Sophie, from Hertfordshire, is now using social media to connect with other people with the condition and find support through her blog and an Instagram account.
“On your own, it’s harder but when people have the same issues as you have, it helps,” she says.
“It helped me so much. The blog is more for people to read, to understand it more and, for people who have it, to have something to relate to.
“Because it isn’t visible, if you don’t tell anyone, they won’t know. And people don’t realise how much it affects you.”
Dan Howarth, head of care at Diabetes UK, said: “Every day we hear from people with type 1 diabetes who say that often, people don’t understand their condition and think that they brought it on themselves.
“Captioning a plate of food with #diabetes is not helpful.
“What we need is for people to understand the differences between type 1 and type 2 diabetes which may help to avoid this kind of insensitivity and recognise that all types of diabetes are very serious.”
