The observation that social anxiety and depression are linked is solidly grounded in psychological study, and both seem to occur in a number of people who first suffer from either condition. It is not safe to say, however, that both will present themselves in individuals suffering from one or the other. Yet, it is very likely that those who do suffer from some form of anxiety when in public places will also suffer from isolation and depression for the lack of connection with others.
When one develops a fear of speaking in public or of being surrounded by others in general, it is often due to an underlying condition of low self-esteem and self-worth. This often leads to overwhelming thoughts and worry on the part of the individual that others do not like or approve of him, and this belief may later manifest into his own thoughts about himself. This never-ending spiral leads down into a realm of sadness and depression, and creates the link so often studied in psychology on social anxiety and depression. It is not proven that social anxiety and depression are caused by one or the other, but the correlation is established and nevertheless existent.
Social anxiety may also lead to the avoidance of going out in public all together, increasing the likelihood of long-term isolation and disconnection from others. Connecting with others is a major part of learning and growing as a human being, and the isolated feelings associated with being alone that stem from the effects of social anxiety can often bring depression. A psychologist is often needed to help an individual break through her social anxiety and depression to help her lead a better life, one full of active involvement and communication with others. Most emotional work does take time, but with perseverance, an individual can succeed in combating her depression and anxiety.
Techniques which help fight social anxiety and depression include relaxation and meditation, as well as exposure therapy which brings an individual into an uncomfortable situation repeatedly until the brain and body become comfortable with it. Relaxation and meditation techniques are also helpful in clearing the mind as well as providing the body with a way to relax and feel comfortable in social situations and in public. Most relaxation techniques involve setting an anchor which can be used during a social situation to help bring the body back into a relaxed state. It is often recommended by some doctors that antidepressants be taken by those with social anxiety and depression, yet many agree that this should be a last resort.
