Dear Dr., I Have Been Diagnosed As Being Diabetic Though

Dear Dr.,
i have been diagnosed as being diabetic though i was never aware of such a disease.that was when i was struggling with lots of stressful situations in my life at work ,at home ,learning for a degree,looking after
sick parents.i would wish to know now that since at present i am more relaxed and am no longer being bombarded by stess,will i always be a diabetic person. My parents never suffered from diabetes ,but my mum"s sister had diabetes.
