Healthy anger is a response to injustice that is short-lived. Healthy anger basically is your way of saying, “What you did was unfair. I deserve better than that.” Unhealthy anger differs from this in: a) its intensity [There may be insults or a temper tantrum, for example.]; b) its duration [It can last for months or years.]; c) its effect on the one who is angry [This kind of anger can deplete energy and increase anxiety.]; d) its effect on the one who offended [It can lead to the other feeling inappropriately attacked.]; and e) its effect on others [The one with unhealthy anger can displace the anger onto unsuspecting other people.].
