Anxiety state is a state between normal anxiety and anxiety disorder. Normal people also experience nervousness and anxiety when things go wrong. However, anxiety state is a state of fear, nervousness and anxiety about the future without clear reasons, and the condition has not yet reached the degree of anxiety disorder, which is clinically manifested as nervousness, anxiety, chest tightness, palpitations, and even systemic dysfunctional performance such as hand trembling and insomnia. Through self-mindedness, part of it can return to normal, but if the anxiety state persists, it may develop into anxiety disorder.
