It is a 50 minute session done 2 times per week, 1 on 1 (yourself and a psychologist).
It is about bringing your deepest thoughts to a conversation under guidance. The main purpose is to learn what is the REAL source for your anxiety/depression/low self esteem.
For example, in my panic attacks i feared that i will get peralized for life, after 4 sessions we figured that the underlying cause for thosr panic attacks is my desire to be different from my father.
