Anxiety 

Anxiety is a feeling of worry, fear, or unease that can be caused by a variety of factors, including stress, trauma, genetics, and medical conditions such as an anxiety disorder. Anxiety can manifest as physical symptoms such as rapid heartbeat, sweating, and trembling, as well as psychological symptoms such as irritability, difficulty concentrating, and avoidance behaviors. Treatment for anxiety depends on the underlying cause and may involve medication, therapy, or other interventions to improve coping skills and reduce stress.
