What is the Main conflict on problem , faced by the main character ? in novel wake up missing by Kate Messner

The main conflict is the ability to sustain identity in the face of not only a brain injury but excessive experimentation. Catherine must not only conquer the injuries that leave her incapacitated with headaches and dizziness but find herself as well. Until she finds herself, she will never be able to escape the clinic or the doctors who show no signs of helping..... of course, "helping" isn't really in their prescription anyway.
