Hi Snodger,
Sorry it took me while to reply. Definately good luck with the paper.
My experience, if it will be any help, is a mixture of all the other posts. I was diagnosed at 21 so not a teenager but a young adult and I spent a year of misdiagnosis and being made to feel like a hypochondriac before finally being told i was diabetic. Since that time I have been given a whole host of contradictory information and often bad advice so my confidence in the medical proffession was not high. Secondly, I do feel guilty. I feel I have failed if my HBa1c is not good. On top of this, people who know you are diabetic constantly say "oh you shouldnt be eating that should you?" etc so if you do have the odd treat, even though you are covering it with the correct insulin you feel bad. And thirdly during visits to the clinic when you tell them you have problems youa re often told "its common for diabetics and there is nothing you can do other than to maange your control better".
Not to forget of course that Diabeties medical care is relativley new and is constantly changing and improving so often this becomes very confusing and scary. i would imagine this is certainly a problem for the elderly so maybe this is another reason people dont attend.
I do and alway have attended but I can see why some might not want to for these reasons.
Hope it helps and good luck.
