I'v had type one diabetes for 11 years and my whole family and i have noticed that when my blood sugar is high i tend to get angry at a drop of a hat over things i normaly wouldnt. It's being questioned by my boyfriend now, he thinks its just a personal problem and i use high blood sugar as an excuse. So now im questioning it. Its just been an understanding when i was growing up that when my sugar is high then im irritable and i need to take care of it and try not to talk to people until it is down. Ha ha.
