عصبی (Nervous) refers to a state of heightened anxiety or apprehension. It often occurs in situations where a person feels pressure, such as before a public speaking event or during an important exam. This feeling can manifest physically through symptoms like sweating, trembling, or a racing heart. In a broader context, the term can also relate to the nervous system, which is responsible for transmitting signals throughout the body. The nervous system plays a crucial role in how we respond to stress and manage emotions, influencing our overall mental and physical well-being.
