More than shyness, this disorder causes intense fear about social interaction, often driven by irrational worries about humiliation (e.g. saying something stupid or not knowing what to say). Someone with social anxiety disorder may not take part in conversations, contribute to class discussions or offer their ideas, and may become isolated. Panic attacks are a common reaction to anticipated or forced social interaction.
Warren: So if you’re walking down a dark alley, you are probably thinking that there could be potential danger; that anxiety of anticipation, the feeling in your stomach, the elevated heart rate. But if you’re walking down that alley and somebody jumps out with a knife, then you’re likely to have a panic attack — an overwhelming urge to escape a situation that is dangerous.
Says Clyman: "You might start to consider your emotions as changing experiences that are always fluctuating. When we feel distressed, it can seem like the distress is going to go on and on forever until we emotionally combust. But instead, emotions act more like a wave, at times increasing and becoming more intense. But inevitably they'll reach a plateau, subsiding and finally passing."
Many medical conditions can cause anxiety. This includes conditions that affect the ability to breathe, like COPD and asthma, and the difficulty in breathing that often occurs near death. Conditions that cause abdominal pain or chest pain can cause anxiety and may in some cases be a somatization of anxiety; the same is true for some sexual dysfunctions. Conditions that affect the face or the skin can cause social anxiety especially among adolescents, and developmental disabilities often lead to social anxiety for children as well. Life-threatening conditions like cancer also cause anxiety.
Characterized by the development of certain trauma-related symptoms following exposure to a traumatic event (see "Diagnostic criteria" below). While most people experience negative, upsetting, and/or anxious reactions following a traumatic event, a diagnosis of PTSD is made when symptoms and negative reactions persist for more than a month and disrupt daily life and functioning. Symptoms are separated into four main groups: re-experiencing, avoidance, negative cognitions and mood, and hyperarousal. The specific symptoms experienced can vary substantially by individuals; for instance, some individuals with PTSD are irritable and have angry outbursts, while others are not. In addition to the symptoms listed below, some individuals with PTSD feel detached from their own mind and body, or from their surroundings (i.e., PTSD dissociative subtype).
Generalized anxiety disorder involves persistent and excessive worry that interferes with daily activities. This ongoing worry and tension may be accompanied by physical symptoms, such as restlessness, feeling on edge or easily fatigued, difficulty concentrating, muscle tension or problems sleeping. Often the worries focus on everyday things such as job responsibilities, family health or minor matters such as chores, car repairs, or appointments.
Many people don't know that their disorder is real and highly responsive to treatment. Some are afraid or embarrassed to tell anyone, including their doctors and loved ones, about what they experience for fear of being considered a hypochondriac. Instead they suffer in silence, distancing themselves from friends, family, and others who could be helpful or supportive.
Selective mutism: A somewhat rare disorder associated with anxiety is selective mutism. Selective mutism occurs when people fail to speak in specific social situations despite having normal language skills. Selective mutism usually occurs before the age of 5 and is often associated with extreme shyness, fear of social embarrassment, compulsive traits, withdrawal, clinging behavior, and temper tantrums. People diagnosed with selective mutism are often also diagnosed with other anxiety disorders.
