Agoraphobia is an anxiety disorder which primarily consists of the fear of experiencing a difficult or embarrassing situation from which the sufferer cannot escape. Panic attacks are commonly linked to agoraphobia and the fear of not being able to escape a bad situation.[20] As the result, severe sufferers of agoraphobia may become confined to their homes, experiencing difficulty traveling from this "safe place".[21] The word "agoraphobia" is an English adoption of the Greek words agora (αγορά) and phobos (φόβος). The term "agora" refers to the place where ancient Greeks used to gather and talk about issues of the city, so it basically applies to any or all public places; however the essence of agoraphobia is a fear of panic attacks especially if they occur in public as the victim may feel like he or she has no escape. In the case of agoraphobia caused by social phobia or social anxiety, sufferers may be very embarrassed by having a panic attack publicly in the first place. This translation is the reason for the common misconception that agoraphobia is a fear of open spaces, and is not clinically accurate. Agoraphobia, as described in this manner, is actually a symptom professionals check for when making a diagnosis of panic disorder.
Had my first panic attack today and wanted to be sure about what I was experiencing. I sat there crying hysterically, hyperventilating, chest shaking, my hands went very numb. Took me about 10 minutes to get sort of calm, sat in the shower for about half an hour afterwards to fully calm myself down. Every time I tried to focus on my breathing and taking longer breaths I would start hyperventilating again. Felt like I was choking, awful awful experience.

If you have a debilitating fear of being seen negatively by others and humiliated in public, you may have social anxiety disorder, also known as social phobia. Social anxiety disorder can be thought of as extreme shyness. In severe cases, social situations are avoided altogether. Performance anxiety (better known as stage fright) is the most common type of social phobia.
Anxiety is associated with abnormal patterns of activity in the brain. One way to treat anxiety is to directly target abnormal nerve cell activity. Neuromodulation or brain stimulation therapy is a non-invasive and painless therapy that stimulates the human brain. In some recent clinical trials, patients that did not respond to more traditional forms of treatment (i.e. medication) showed a reduction in symptoms of depression and anxiety. There are two main types of neuromodulation:
In fact, some studies have suggested that people with chronic anxiety disorders have an increased prevalence of CAD—that is, chronic anxiety may be a risk factor for CAD. So doctors should not be too quick to simply write the chest pain off as being “simply” due to anxiety. They should at least entertain the possibility that both disorders may be present and should do an appropriate evaluation.

Social anxiety disorder (previously called social phobia): People with social anxiety disorder have a general intense fear of, or anxiety toward, social or performance situations. They worry that actions or behaviors associated with their anxiety will be negatively evaluated by others, leading them to feel embarrassed. This worry often causes people with social anxiety to avoid social situations. Social anxiety disorder can manifest in a range of situations, such as within the workplace or the school environment.
