Probably don't read the below if you're feeling vulnerable and upset. But I think it's important to flag - especially due to the number of parents with young diabetic girls on this thread.
I don't think T1 Diabetes has to put limits on anybody's life. At all. But in my (admittedly only observed) experiences it can be totally devastating when combined with poor mental health.
One of my very close friends and one of my oldest daughter's friends both have a condition called Diabulimia. It doesn't get as much publicity and awareness as it should so, if you aren't aware, it's the most dangerous of eating disorders. Sufferers omit insulin which causes rapid weight loss. It often comes hand in hand with more traditional eating disorders but not always. For some people, if they're desperate enough to lose weight, they take little to no insulin at all which obviously has dire consequences that don't need spelling out. There is one small charity called DWED (Diabetics With Eating Disorders) which is doing incredible work relative to its size and funding but help for diabulimics and T1 diabetics with other eating disorders is pretty woeful - hospitals do a really bad job of managing the concurrent conditions.
As well as having diabulimia, bulimia and anorexia, my friend also has severe depression and anxiety which she attributes in part to her diabetes. She has severe eye, feet and liver damage. Of course it might all have happened to her anyway but I wonder if, with a bit more guidance and help to manage the diabetes when she was 8-12 years old, she might not have ended up in the desperate position she is in now.
I know most T1 diabetics have happy and healthy lives. I know there is no reason to think any of the children mentioned on this thread won't. But they are statistically at much more risk of mental health issues so it's worth knowing that they need that extra care and attention growing up.
