Thinking about the character Lexie Grey(played by actress Chyler Leigh) from the ABC series Grey's Anatomy, what could a clinical assessment of this character be like? What would be the possible traumas presented by this character and what could a clinical psychologist's diagnosis be like regarding her condition with these possible traumas and what could be the possible treatments?

What/how should be the clinical psychologist behave like in the first therapy session with this character?
