Diabetes is a disease, not an excuse.
Yes, my ex had anger issues. He ended up committing suicide 4 months before his 30th birthday. I don’t think the diabetes helped his problems. I did notice there were often correlations between low blood sugar and outbursts...shortly after he died, I read that diabetics had higher levels of depression than the GP.
However, one of my coworkers is diabetic and as mild mannered as they come, so there is no excuse.
Is he pushing up roses these days or does he use a walker to get around?
