Hi
@Lainne1970, diabetes is higher risk (vunerable as the government puts it), but not extremely high (extremely vunerable), so we should be socially distancing. Unless you have other conditions which increases your risk further then you won't be getting a letter.
Personally I'm choosing to self isolate for 12 weeks but I don't work and am (obviously) not a key worker so that's my own decision and I don't have to argue with anyone about whether I am safe to go out or not! Obviously if you are a key worker and your employer wants you to carry on working, that makes things more difficult without a letter from the nhs.
