Hi Lauren, I myself am a Type One Diabetic and have been since the age of 2 now 56 so a bit of first hands on experience
As a bonus I have ADHD as well!
I remember as a young child never being able to concentrate with my school report stating the typical ADHD trait of 'could do better if paid attention'.
There was absolutely zero knowledge of this condition as well back then, at least that my school knew about.
I myself never really knew that I had ADHD, but I did know, I had diabetes and that is what I concentrated more on.
You mention that it's 'heartbreaking to see him struggling so much mentally' which is fully understandable.
How does he respond when you ask him how does he feel?
Pretty sure here that you have contacted the NHS for futher help, the Diabetes UK and the ADHD Foundation.
Enjoy your day
Does your child have type 1 diabetes and ADHD? We are starting the process to get our 7 year old diagnosed with ADHD, it’s very rough as a parent and heartbreaking to see him struggling so much mentally.
