Which of the following is a common symptom of depression?

Persistent sadness or loss of interest in activities is indeed a hallmark symptom of depression. This symptom can manifest as a feeling of emptiness or hopelessness that lasts for a significant period of time. Individuals experiencing depression often find that they no longer derive pleasure from activities that previously brought them joy, leading to a marked decrease in participation in social or recreational events. This core symptom reflects the emotional and motivational aspects of depression, significantly affecting one’s daily functioning and quality of life.

In contrast, the other choices present traits that are not associated with depression. Increased energy and motivation, heightened self-esteem, and enhanced social engagement are typically reflective of a more positive mental state, which stands in stark contrast to the experiences of those suffering from depression.
