Until recently, Jerry had always enjoyed being on his high school debate team, which had won several awards. But yesterday, as Jerry prepared for next weeks event, he began to experience a heightened sense of nervousness. He noticed tightness in his chest and he felt dizzy. He had difficulty controlling his rapid breathing and began to feel an intense need to go outside for air. It is most likely that Jerry was experiencing symptoms of:.
1. obsessive-compulsive disorder.
2. a panic attack.
3. agoraphobia.
4. post-traumatic stress disorder.

It is most likely that Jerry was experiencing symptoms of a panic attack.

Explanation:

A panic attack can be described as a sudden feeling of fear in an individual due to which several physical reactions are triggered. Panic attacks might be very severe and a person might think that a person is losing his breath and will die or it feels like a heart attack is occurring. A panic attack is not provoked and hence is unpredictable.

As Jerry also feels high sense of nervousness which was not provoked, we can assume that Jack experienced a panic attack.
