Problem: Based on the client description, what would be the most likely diagnosis? Liana is a 16-year old high schooler who was referred to your agency from the hospital, after being seen in the emergency room with symptoms of shortness of breath, chest pain, and dizziness. This was the first time Liana experienced such symptoms, and the doctors reported no abnormal medical findings. Liana describes herself as "high-strung" and a "perfectionist". Although she excels in school, she attributes her success to her fear of failure and worries about what others will think of her if she is not perfect. In addition to worries about her performance, Liana frequently has trouble sleeping, because she becomes worried about what would happen if an intruder broke into her home or if a family member had a medical emergency in the middle of the night. She cannot remember exactly when she started feeling so tense, and believes it's "just the way I am". Need Assignment Help?
