There is a clear difference between anxiety disorders and psychiatric disorders, the most significant difference being the difference in clinical presentation. Anxiety disorders are mainly characterized by nervousness, anxiety, worry, fearfulness and quietness. It is accompanied by somatic discomfort, such as headache, dizziness, nausea, vomiting, palpitations, panic, along with flushing or sweating, tremor, and other problems. The clinical manifestations of the above behaviors are mainly fidgeting, even walking back and forth, sitting nor standing nor discomfort, etc. The main manifestation of psychosis is hallucinatory delusions, such as hallucinations, delusions of victimization, delusions of relationship, or severe behavioral disturbances, as if one is immersed in the inner world and is separated from the whole environment. There are other differences, for example, anxiety disorders have clear self-awareness, but psychiatric disorders generally do not have good self-control, that is, patients with psychiatric disorders are aware that they have anxiety problems for anxiety disorders, and they also have very painful feelings. But patients with mental illness have no self-awareness, do not know they have mental illness, and rarely have painful feelings, which is also a very obvious difference.
