Imagine learning your teenager, for example, had been yelling demeaning slurs at the girls in his class, harassing them and calling them names.

And that he’d been secretly using his social media accounts to go on late-night rants against perceived enemies, attacking their looks, and again, calling them names in unending, seething, rambling posts.

Or that he’d been increasingly susceptible to bizarre and otherwise implausible conspiracy theories, and was spreading them unprompted to anyone who would listen.

Presumably, you’d be very, very concerned. These aren’t normal behaviors, nor are they signs of a well-adjusted, healthy and happy person. They are, rather, signs of a person who has lost the ability to manage their emotions.
