There are some common symptoms or experiences of social anxiety. Common markers of anxiety disorders include:  Excessive self-consciousness and anxiety in everyday social situations that generally others would not find overly stressful. Extreme worry about social situations for days, weeks, or even months beforehand. Intense fear of being watched or judged by others, especially people you do not know. Avoiding social situations to a degree that limits your activities or disrupts or otherwise negatively impacts your life. Fear of humiliation. Fear that others will notice that you are nervous and react negatively. While experiencing anxiety affects the way you feel emotionally, your body creates triggers to clue you in on how you’re feeling. People with social anxiety may experience:  Blushing Shortness of breath or difficulty breathing Nausea, or “butterflies” Shaky hands or voice Racing heartbeat Sweating Feeling dizzy or faint Different people with social anxiety have different triggers, although many are pretty common. By knowing what causes you to react with anxiety, you can start to process these experiences in a more positive manner. It may be obvious, or sometimes seemingly random. Sometimes keeping a journal can help pinpoint common experiences. For example:  Do you feel anxiety when you walk into a classroom? Is it the same for math class as it is for art class? Do certain people, like your boss or coworkers, trigger anxiety when you interact with them? Do you feel anxiety in social situations? Is it the same for a restaurant as for a concert? Is a group of close friends different than strangers? Do you always sit by yourself at lunch, rather than asking to sit with others? Do you always turn down invitations to parties? Do you avoid family get-togethers? Do you avoid using public restrooms? Some other common triggers include: Meeting new people Being the center of attention Being watched while doing something Making small talk Being called on in class Making phone calls Eating or drinking in public...
