A person with social anxiety disorder may appear tremulous in a social situation. They may have poor eye contact. If you were to shake their hand, it may appear cold and clammy. In general, these individuals will avoid situations where they have to meet people, where they may have to speak, and in some cases where they even have to eat in the presence of others. Additionally, after this pattern of behaviour, these individuals often develop very low self esteem because they're aware that they have this disability. They're also aware that their fear and worries are unreasonable but yet they feel helpless to do anything about it.
