10 10 were feeling guilty and confused. She felt guilty when she was abandoned by her mother. She blamed herself as the cause of her mother left her behind. The confusion happened when Sheila was to decide to stay in a special education class or to join a regular class which means that she had to separate from Torey. On the other hand, joining in the regular class was her dream. Furthermore, her research findings showed that there were some causes of Sheila’s psychological conflicts.
