Anxiety disorders are the most common of all the mental conditions and affect nearly 30 percent of adults at some point in their lives. Anxiety isn’t as simple as you might think, though. There are five main types of anxiety, each with its symptoms. Fortunately, anxiety disorders are very treatable and can be manageable with the right treatment plan that includes quality psychotherapy. Anxiety disorders can include Generalized Anxiety Disorder (also known as GAD), Panic Disorder, Post-traumatic Stress Disorder (also known as PTSD), Social Anxiety, Separation Anxiety, Obsessive-Compulsive Disorder (also known as OCD), Agoraphobia and Phobias.
