Is this true? Naive Googling yields this, which suggests (non-authoritatively) that blood sugar and moods are indeed linked (in diabetics, but it’s presumably true in the general population). However, despair is not noted and the effects generally seem milder than that (true despair is a rather powerful emotion!)
Blood sugar is very closely linked to self-control, including suppression of emotion. While this may appear to be a different thing, it isn’t: when you include feedback loops and association spirals, a transient, weak emotional distraction can become deep and overwhelming if normal modes of suppression fail.
Anecdotally: I’m not diabetic that I know of, but my mood is highly dependent on how well and how recently I’ve eaten. I get very irritable and can break down into tears easily if I’m more than four hours past due.
