Anxiety
Anxiety is a feeling of worry, nervousness, or unease about something with an uncertain outcome. It can manifest in both physical and emotional symptoms, often including increased heart rate, restlessness, and difficulty concentrating. While it is a normal response to stressful situations, excessive anxiety can interfere with daily activities and may require professional help to manage effectively.
