from a business trip 4 weeks ago. The trip was stressful as it involved giving multiple presentations, which the patient feared were not

up to his boss’s standards. However, since his return, instead of working on current projects with assigned deadlines, he has spent

hours developing new computer programs. His wife reports that he hardly sleeps and is increasingly anxious and irritable, behavior

that is uncharacteristic of him. Last week the patient became angry when she was deeply skeptical of his idea to leave his job and

start his own internet company. The patient has a history of attention-deficit hyperactivity disorder, for which he was treated with

marijuana on occasion, which “helps me feel less anxious.” Family history is significant for anxiety and depression in his mother. On
