I have experienced a lot of bullying from healthcare professionals other than my GP. I have ended up crying, several times. A consultant shouted at me for wearing low heeled closed-toe slingbacks, a nurse tried to prevent me leaving a room, physically. I've been told not to eat cakes and biscuits (I didn't before diagnosis anyway) by umpteen nurses and to eat porridge also, even if they are way fatter than me.
I don't tell people that I have diabetes in real life or social media other than here because people are so judgmental. I get really annoyed with my mother for telling people, especially when her friends start recommending diets to me !
If I test away from home and some one asks I tell them I have carbohydrate intolerance. That works, I get sympathy without judgment.
