Personally I find that my moods swings in tandem with my BG levels. I am LADA fairly newly diagnosed so am still "settling in" but when BG is high my mood becomes more angry firstly at me because my BG are so uncontrolled and then with medics who are supporting me. Frustration I suppose is the main sentiment and then I get very low, dark moods, very dark indeed,when I start to work out how best, for me, to get out of this diabetes millstone which I now have round my neck.
I suppose it is for each of us to try and manage this as best we can.
