However, before we discuss particular treatments for anxiety, it might be beneficial to examine the common indicators. Anxiety will manifest in emotionally, psychologically and physically. Anxiety is essentially the flight, freeze or fight workings of our body and mind. It is a hardwired survival response to stress.
