A psychologist with diabetes discusses this in the article below. Starting in 1945 I did not tell anyone about my diabetes except my relatives, a few neighbors, and teachers in school. My mom did the telling, I kept quiet about it. People did not seem to know anything about diabetes wen I was young. My teachers had not heard of diabetes. I did not tell friends about it until college, but they did not understand it. I never really opened up about my diabetes until 2006, online, and in public. It was such a relief to come out of hiding and educate people about diabetes. I try to do that online, and in giving speeches to groups.
If you keep your diabetes a secret, what is your reason for doing that?
