Case 1 :
Ms. M. is a 19 year old student. She decided not to attend her university classes on the first day because she knows that in some classes the professor will instruct them to go around the room and introduce themselves. Just thinking about sitting there, waiting to introduce herself to a roomful of strangers who will be staring at her makes her feel nauseous. She knows she won't be able to think clearly because her anxiety will be so high, and she is sure she will leave out important details. Her voice might even quiver and she will sound scared and tentative. The anxiety is just too much to bear, so she skips the first day of class to avoid the possibility of having to introduce herself in class.
Case 2 :
Mrs. A., a 32 year mother of two kids hates to stand in line at a crowded bus station because she's afraid that everyone is watching her. She knows that it's not really true, but she can't shake the feeling. While she is shopping, she is conscious of the fact that people might be staring at her from the big mirrors on the inside front of the ceiling. Now, she has to talk to the person who's checking out her groceries. She tries to smile, but her voice comes out weakly. She's sure she's making a fool of herself. Her self-consciousness and anxiety rise to the roof.
