Answer:
Jack's fear of having another panic attack and his avoidance of leaving his house suggest that he may have agoraphobia.
Step-by-step explanation:
Agoraphobia is an anxiety disorder that involves fear and avoidance of situations or places that may be difficult to escape from or where help may not be available if a panic attack occurs. People with agoraphobia often avoid situations such as leaving their home, using public transportation, or being in crowded places. Agoraphobia can be a debilitating condition. However, it can be effectively treated with psychotherapy, medication, or a combination of both. Jack should receive a proper diagnosis and treatment.
