Anxiety is a mental health diagnosis that includes generalized anxiety disorder and social anxiety disorder and may be co-diagnosed with depression. Although many of the symptoms of anxiety are within the brain, such as excessive worrying, insecurity and being distracted, the symptoms of high anxiety may also be physical in nature. People who believe they are experiencing anxiety beyond what is normal or are unable to do the things they normally do should contact their doctors, as there are both medical and alternative treatments for anxiety disorders.
