Yes. If you feel that you may suffer from some of the symptoms of seasonal affective disorder, there are a number of online self-assessment seasonal affective disorder tests you can use to check whether you may be suffering from SAD.
In general, SAD assessments take the form of a short questionnaire that only takes a few minutes to complete. Many of the assessments include questions on a scale rating of 1-5 for you to choose from.
If, after taking a test, you discover that you might be suffering from seasonal affective disorder then you should contact your doctor immediately so that they can confirm or deny a diagnosis and suggest the best course of treatment.
