A 29-year-old woman with history of bipolar disorder is brought to the emergency department by ambulance after her wife called 911.

Starting 3 days ago, the patient developed nausea, vomiting, and diarrhea and called out sick from work. The patient’s wife is not sure what medications she has been taking.

An 18-year-old woman in her freshman year of college presents to her student health center for evaluation of anxiety. She says that she becomes overwhelmed and “paralyzed” at the thought of trying to meet new people. She has been skipping her introductory classes that involve participation, as she is terrified that she will be called on and will “make a fool of myself.” She is also afraid that she blushes and “pours sweat” when she must speak with someone in person, so she does everything she can via text or online. Upon further exploration, she reveals that these concerns have been present since she was around 15 years old. She feels “discouraged” but denies depressed mood, and she continues to enjoy drawing and journaling. She denies being concerned about her finances, her physical health, or her safety. What is the most accurate diagnosis?
