I cannot imagine not feeling down when you are diagnosed with diabetes. It requires a long and gradual adjustment period to reach the point where you can feel a new kind of normal. Diabetes can be controlled and you can have a very normal life, after adjustment. I have been a diabetic since I was 6 years old, so I cannot remember life before diabetes. It is been a wonderful life for me, and I have accomplished everything I have wanted to do. It can be that way for you too. Give it time, educate yourself and give it all you've got. Get control and have a great life!
