Most of our character is created in early childhood and is often influenced by the early trauma or attachment raptures in parent/child relationships. Unconscious patterns of behavior are created at that time and they “rule” our lives from that point on. We tend to recreate those patterns unconsciously in our relationships and in the ways we deal with the world.
We come to therapy because we began experiencing certain symptoms, such as depression, sleeplessness, apathy, anxiety, etc. We need to understand that any given symptom is created because it was necessary for the psyche to have it at the time, that it corresponds to some unconscious emotional material and it has a purpose. This is called the emotional truth of a symptom.
The necessity of the symptom's creation lies in the recognition that suffering from the symptom feels more tolerable than the suffering unconsciously expected by the psyche from not having the symptom. In other words the initial pain was so unbearable that brain needed to compartmentalize the initial pain and create a symptom to cover it.
