Final answer:
The psychological state that includes symptoms like anxiety, depression, and fatigue is known as the stage of exhaustion in the general adaptation syndrome (GAS). It is the response to prolonged stress characterized by physiological and psychological effects. So, the correct answer is option 4.
Step-by-step explanation:
The psychological state that results in anxiety, depression, confusion, helplessness, hopelessness, and fatigue is known as the stage of exhaustion in the general adaptation syndrome (GAS), which was proposed by Hans Selye. The GAS consists of three stages, starting with an alarm reaction (an immediate response to stress), followed by a stage of resistance (where the body adapts to the stressor), and finally to the stage of exhaustion.
If stress continues for a long term, the body may suffer from symptoms such as depression, impaired immune response, severe fatigue, or even life-threatening conditions mediated by hormones like cortisol released due to signals from the HPA axis.
Out of the given options, the correct one in reference to these symptoms is the general adaption syndrome. The other options listed do not describe the full scope of the symptoms mentioned in the question.
