Final answer:
The experience of basic anxiety involves feelings of being alone in a hostile world, often connected to the fight-or-flight response, which can have negative health consequences when triggered by modern psychological stressors.
Step-by-step explanation:
The experience of basic anxiety is the feeling of being alone in a hostile world. Anxiety is often tied to the body's fight-or-flight response, initially evolved to protect us from physical threats. Today's psychological stressors, such as giving a presentation or facing challenging social situations, can trigger this response even when there is no physical danger present.
The subsequent physiological reactions can lead to feelings of fear, insecurity, and a sense of abandonment that contribute to one's experience of basic anxiety. This type of heightened anxiety may increase susceptibility to health issues like heart disease and impairment of immune function due to chronic stress.
