Seasonal affective disorder (SAD) is a type of depression related to seasonal changes. People with SAD usually begin to experience feelings of hopelessness, sadness and lack of interest in activities, starting in the fall and winter. Though it is less common, some people with SAD begin to feel symptoms in the spring and early summer.

Some people may try to soothe SAD symptoms with drug and alcohol abuse, but substance abuse usually exacerbates mental health conditions. If you have SAD, you aren’t alone, and treatment is available.
