Depression is a mental illness characterized by feelings of profound sadness and lack of interest in enjoyable activities. Depression is a persistent low mood that interferes with the ability to function and appreciate life. The range of symptoms may be both physical and emotional and can last for weeks, months or years. Seasonal Affective Disorder or SAD generally occurs from October through March and the symptoms generally mimic those of generalized depression. However, the condition may also include characteristic symptoms of what NAMI calls “recurrent winter depression” and includes food cravings, weight gain, fatigue and oversleeping.
Symptoms for holiday blues are milder and temporary and generally triggered by money worries, thoughts of loved ones in distance locations, thoughts of loved ones who have passed or even illness.
