Dr. Wren is in the process of diagnosing Lily’s psychological disorder. When he asks Lily a few questions about her symptoms, Lily reveals that she experiences alternating episodes of euphoria and distress. On some days, Lily claims that she feels like she is capable of doing anything in the world. During this phase, she can’t sleep, feels restless, and is extremely excitable. On the other days, Lily feels utterly worthless and miserable. During this phase, Lily lies in bed all day and is troubled by morbid thoughts. In the context of disorders involving emotion and mood, it can be inferred that Dr. Wren is likely to diagnose Lily with ________

According to my research on different disorders studied by medical professionals, it can be said that based on the information provided within the question on the symptoms that Lily is going through - Dr. Wren is likely to diagnose Lily with Bipolar Disorder. This is a disorder that causes the sufferer to experience widely ranged mood swings that go from depression to extreme highs (euphoria). Which is exactly what Lily seems to be experiencing.
