Which psychiatric condition is often characterized by feelings of sadness?

The condition characterized by feelings of sadness is depression. This mental health disorder is primarily defined by persistent feelings of sadness and a lack of interest or pleasure in previously enjoyed activities. Depression can manifest with a variety of symptoms, including changes in sleep, appetite, energy level, and concentration, as well as feelings of hopelessness or worthlessness.

Unlike the other options, which relate to either physical symptoms or different mental health concerns, depression specifically encompasses the emotional experience of sadness. Anxiety can involve feelings of worry or fear, headaches are physical symptoms often caused by various factors, and wheezing is related to respiratory conditions. Therefore, depression stands out as the condition most directly associated with the experience of sadness.
