A diagnosis of depression is often difficult to make because clinical depression can manifest in so many different ways. Observable or behavioral symptoms of clinical depression also may sometimes be minimal despite a person experiencing profound inner turmoil.

It affects a person’s body, feelings, thoughts, and behaviors in varying ways. Clinical features include low mood, feeling of hopelessness, worthlessness, helplessness, suicidal thoughts, decreased interjet in activities, sleep disturbances etc. Different types of psychotherapy can be effective for managing depressive symptoms.
