Personally, I find it frustrating when non-diabetics make those judgements on my behalf based on mortality rather than including quality of day to day life (with what they might see as well-meaning comments, I do appreciate! By others I mainly mean colleagues or friends).
I don't find it helpful to have an all or nothing approach - mortality or being fully functioning aren't the only options. My glucose levels shoot up with a common cold, and this disproportionately impacts on my daily life. Many other type 1 diabetics are lucky and wouldn't notice this though so don't have this consideration.
Once lockdown has been eased, I would much sooner be able to continue minimising social contacts while seeing friends and family, and continue being able to eg exercise and have energy to maintain good management of my diabetes. The implications of anything but asymptomatic covid-19 could prevent me from doing those things.
So for me the worry is not hospitalisation or death, it is the impact on my glucose levels which could strip me of time and energy to do anything but work. Everyone is different of course!
