What are the symptoms of atypical depression?

Atypical depression symptoms include a feeling of melancholy and sorrow, as well as a lack of interest in formerly enjoyable activities. These symptoms are the same for most types of depression. The difference is that with atypical depression your mood can improve temporarily if something positive happens in your life. Other symptoms of this form of depression include tendencies to overeat and/or oversleep, feelings of heaviness in the limbs, and an extreme sensitivity to rejection from others. Additionally, atypical depression symptoms do not seem to be affected by tricyclic antidepressants.
