Desensitization. Systematic desensitization is a technique where a person creates a heirarchy of their fears or phobias. Then a psychotherapist helps the person learn relaxation techniques. Then the psychotherapist exposes the person to the fears or phobias in vitro (in a lab) or in vivo (real life). This process can help a person overcome phobias.
Agree w Dr. Chen. In addition - cognitive behavioral therapy can be quite effective. Take care.
