Is it possible to get rid of social anxiety alone?

Social Anxiety: You need someone to help you make the gradual steps in reducing your anxiety around others. Supportive psychotherapy can be very successful in helping you feel more comfortable around other people. It is very hard to do without support, and with support requires some level of discomfort early in the efforts to get to a place where your social anxiety is reduced. Takes some determination.

CBT: CBT can help you overcome this by helping you manage anxiety and apprehension about social evaluation. It can help you develop a more positive frame of mind, and social skills, (e.g., how to initiation conversations and how to be assertive). Positive thinking and effective behavior could be role played with your therapist in practice settings until you feel comfortable trying then out on your own.
