If you’ve ever gotten “hangry” -- hungry and angry at the same time -- low blood sugar may have been to blame. This happens to some people when they go too long between meals. You may feel angry, upset, lonely, or confused. You may even want to cry or scream.
To feel more like yourself, eat something.
If you have diabetes, it’s important to notice sudden mood changes because you could faint if your blood sugar stays too low for too long.
