I know that there are many types of depression, but had never heard of this. He friend is an extremely intelligent man, and has a wonderful heart. Any information you can provide would be greatly appreciated. Feeling worthless, sitting in a corner are some of the symptoms of depression. I would need more information regarding your friend's symptoms to come to any reasonable diagnosis as there are several types of depressive disorders.
Treatment depends on the particular diagnosis and severity of the condition.
