A psychiatrist can use several ways to help you deal with your social phobia, these can be graded self exposure, cognitive behavior therapy or CBT and social skills training. 

Graded self-exposure

When a person is faced on a terrifying situation, his or her anxiety will start to go away after some time. This approach helps you to do this for yourself, one step at a time. 
In the graded self exposure, the doctor will tell you to create a list of all the situations that you can trigger your fear, and then put them in order, from the least frightening to the most frightening.  

You start with the least frightening situation and, with the support of your therapist, keep yourself there until you stop feeling anxious. You then move on to the next one and so tackle these frightening situations one by one. It is done in stages, each time making the situation a little more intense and frightening. 
  
Cognitive behavioral therapy (CBT)

Social phobia is closely associated with your self concept, the world and the people around you – people can make themselves anxious by the way that they think about situations. This treatment helps you to change the way that you think about yourself and other people.

The therapist will help you to be aware of:

The unhelpful impact on your behavior of thinking about these things all the time  - and the connections between these and your anxiety. 

Any safety behaviors

Any unhelpful rules, assumptions or predictions that you regularly use – and the physical sensations you get when they go through your mind

For example, take the situation when a conversation dries up. If you have a social phobia, you will tend to think it is your fault – you may have the automatic belief that “I never have anything to say” – and so you will start to feel anxious. In CBT, the therapist will try to help you to be aware that it is just as likely that the other person has run out of things to say. This is a more realistic and less worrying way of thinking about the situation. The therapist will help you to test these ideas out in your day to day life.

Social skills training

Social skills training helps people feel more relaxed and at ease when in other people’s company. It does this by teaching some of the simple social skills that we tend to take for granted – like how to start a conversation with a stranger.  You can practice with other people and do what is called ‘feedback’ – people watch themselves practicing on video to get an idea of what they are doing and how they appear to other people.
