Seasonal affective disorder, or SAD, is a type of
depression that occurs during the same
season each year. You may have SAD if you felt depressed during the last two winters but felt much better in
spring and summer.
Almost everyone has dark thoughts when his or her mood is bad. With depression, though, the thoughts can be extremely negative. They can also take over and distort your view of reality.
Cognitive therapy can be an effective way to defuse those thoughts. When used for depression, cognitive therapy provides a mental tool kit that can be used to challenge negative thoughts. Over the long term, cognitive therapy for depression can change the way a depressed person sees the world.
