He feels uncomfortable eating lunch with everyone else at business meetings because he feels as though everyone can hear him chew and worries constantly that he has food on his face or stuck in his teeth.

He is even afraid to use the bathroom at work for fear that others will be in the room with him at the same time. What drug therapy is first-line for his condition? Question options: Selegiline Lorazepam Paroxetine Imipramine
