Final answer:
Johnathon's symptoms suggest he could be diagnosed with social anxiety disorder, a condition marked by persistent fear in social situations causing significant distress or impaired functioning.
Step-by-step explanation:
Given Johnathon's symptoms of feeling very anxious and uncomfortable in various social settings such as the mall, the movies, and going to class, it is likely that he could be diagnosed with a type of anxiety disorder. Specifically, his fear of being out in the open and experiencing anxious feelings in social environments could be indicative of social anxiety disorder (SAD), which is characterized by a significant amount of fear in one or more social situations, causing considerable distress and impaired ability to function in at least some parts of daily life. An anxiety disorder diagnosis would consider the duration and intensity of Johnathon's anxiety, and whether it is a pervasive condition lasting for months, as anxiety disorders involve worry and fearfulness that persist over time and are not just occasional feelings of anxiety.
