Diabetes has only ever affected my concentration when hypo, and I'm not hypo very often. Honestly, I don't have either of those issues. Nor this one. (Yes, I do carry glucose with me, though). Yes, my choice is more limited at restaurants, but it has never caused me to be the centre of attention, I just avoid the stuff I can't eat. My friends and family all know I have diabetes, they don't make a big deal of it or regard me as particularly deprived. This one I agree with, hypos absolutely and totally suck. Having said that, I balance my diabetes so that they don't happen very often. Please beg/bully your diabetic team to change your regime so that you have a better quality of life.
