Is it seasonal affective disorder if you are depressed only on the gray days of winter and not sunny days?

It might be seasonal affective disorder (SAD), but a diagnosis from a mental health professional is essential. SAD is a type of depression that is related to changes in seasons, typically starting in the fall and improving in the spring. Although many people with SAD experience symptoms on gray days, the primary diagnostic criterion for SAD is having symptoms for at least two consecutive winters and not during the summer months. Additionally, several other criteria, such as low mood, loss of interest in activities, changes in appetite or sleep, and difficulty concentrating, must be met for a diagnosis of SAD. If you are experiencing symptoms of depression, consulting with a mental health professional for a proper evaluation and potential diagnosis is important, as other factors may also contribute to your symptoms.
