After about 11 months my VA disability finally went through. I was denied on some claims, one which supprised me. But because there was no history of any illness leading up to it in my records they didnt honor that part of my claim. I may try to appeal.

I think you should get more info from your doctor. Maybe even show him/her your military health records. Just because you were not diagnosed with Diabetes in the Military, doesnt mean that you didn't have or were treated for symptoms related to it. They may be able to find it that way. For example, I was diagnosed with Crohn's disease 2 years after I got out in 2007. But I had some stomach issues while I was in, and through pictures taken of my intestinal walls they were able to see Crohn's in my military record dating back to 2002.

You may also want to find a near-by DAV representative and talk to them about your condition. Show them your records too, they may be able to find something else you qualify for - they work hard for you for free.
