Paula has not left her house for several months. when she tries to go out, she experiences great anxiety. she says she is afraid that if she leaves her house to go somewhere, she will not be able to get back. before all this started, paula seemed fairly normal except for having several episodes where, for no apparent reason, her heart started pounding, she started to sweat profusely, and she experienced all the symptoms of fear and terror. one of the reasons she is afraid to leave the house is because she is afraid she will have one of these episodes again. (hint: there are two specific diagnoses here.)
