It is finals week and you have been studying for a big exam. Your performance on this exam is important to your overall grade. During this time, you have neglected your sleep and nutrition needs. You seem more irritable than usual to your friends. What are you most likely to be experiencing?

Stress

Explanation:

Stress is a type of emotional response a person has to a certain type of stimulus. The response is caused by the body's reaction to a threat, hurdle or barrier which is presented to a human.

Here, I am experiencing mental discomfort because of the thought of not being able to perform well in the exam. This is a psychological barrier. This causes me to react to everything in negative manner.

Hence, the question is referring to stress.
