Overview
Depression and anxiety disorders are common mental health conditions that affect mood, thoughts, and daily functioning. With early diagnosis and proper treatment, most individuals can effectively manage symptoms and lead fulfilling lives.
What is Depression
Depression is a common and serious mental health condition characterized by a persistent feeling of sadness, loss of interest or pleasure in daily activities, and a range of emotional and physical symptoms that interfere with normal functioning.
What is Anxiety Disorder
Anxiety disorders are a group of clinically significant psychiatric conditions characterized by excessive, persistent and disproportionate fear or anxiety that is not commensurate with the actual threat and leads to functional impairment. These include generalized anxiety disorder, panic disorder, social anxiety disorder, and specific phobias.
Both conditions can occur together and significantly impact physical and emotional well-being.
