What is a hallmark symptom of behavioral anxiety?

Irritability is considered a hallmark symptom of behavioral anxiety because it reflects the heightened sensitivity and stress that individuals may experience in situations that trigger their anxiety. When someone is anxious, they can become easily frustrated or upset, often responding with irritability towards others or themselves. This symptom is particularly relevant in the context of behavioral anxiety, which is closely related to stress responses in social situations.

While dry mouth, obsessive thoughts, and confusion can also be associated with anxiety, irritability is more directly tied to behavioral manifestations and emotional regulation difficulties that arise from anxiety. This symptom may also affect interpersonal relationships, as those experiencing irritability due to anxiety may struggle to communicate effectively or manage their responses in social environments.
