Marla is a 24-year-old woman who recently graduated from college and began a new job at an advertising firm. She has come to see you, a behavior analyst, for what she reports as extreme fear of social situations. When she is in a group of 3 or more people, she says her heart starts racing, she gets sweaty, she stutters, and she shakes. In college, Marla tripped and fell in front of the class on the way to giving a class speech. Some of the students laughed. Afterwards, she began avoiding parties and large gatherings and tended to keep to herself. Now that she is working, it is becoming increasingly difficult for her to avoid social situations. Her boss and co-workers expect her to attend office functions and client parties, as networking is a large part of the job. Marla is very artistic and creative and has already designed several successful ads for clients, but she is afraid that she will lose her job because of the difficulties she is experiencing socially.
