been there, totally understand how horrible it feels being judged by others, whether it's family or friends or school/workplace.
The key is to get your own head around what being diabetic means to you. It means hard work and there's not much to be done about that. But it also means you are one of an amazing bunch of people who have had to develop a range of specialist skills and abilities that people don't even realise we have. It really REALLY isn't anything to feel bad about or inadequate about.
Can you get your family to get off your back for just a month to let you 'own' your diabetes properly? Yes they love you etc and that's why they are on your back, but it's YOUR illness and so it's ok to tell them that you need to come to terms with it without their judgement. If they don't have type 1 then they don't know, and they will never know, what you are going through, and it's not about them it's about you. Get them to try not to even mention diabetes for a whole month - tell them if they do, they have to put a pound in a box and at the end of it you get the money. But in the meantime, use that month to test and inject and understand how the testing can be helpful to you. If you get high readings, don't think of them as 'bad'. Try and work out why they happened. Testing is just something to help you learn so YOU feel well and stay well. You aren't doing it for anyone else and you don't have to tell anyone else what those readings are.
Also think about what would happen if you told people you were diabetic. What's your worst fear? What did happen, when you told that one person? Can that person help get the word round without it being a big thing?
