"What Is Anxiety?
Anxiety is related to fear, but is not the same thing. The diagnostic manual of psychiatry (DSM-5-TR) defines fear as “the emotional response to real or perceived imminent threat, whereas anxiety is anticipation of future threat.” Both can be healthy responses to reality, but when excessive, they can become disorders."
