When you're exceptionally tired but unable to get sleep, it doesn't take much to set you off. Situations that normally would be manageable may suddenly seem much more irritating. There's a good chance it's because you're sleep deprived.

One study showed that children who slept less than 10 hours in a day were 25 percent more likely to misbehave [source: The Franklin Institute].

Sleep deprivation increases your odds of experiencing feelings of depression, burnout and decreased empathy. Those who are already depressed or have other underlying mental health disorders may find those problems exacerbated by lack of sleep.
