I assume you're referring to Major Depressive Disorder in the DSM-IV, because there is no disorder listed in that book as "depression." Major Depressive Disorder isn't a natural state of mind and never was. It's a terrible debilitating illness, often caused by a chemical imbalance that can't be treated (as in my case) without medication. To say that it's simply the result of my life not going as I want it to is insulting. And most modern anti-depressants do not degrade your overall quality of life in the long run... there is no evidence to prove that.
where's the evidence that depression is caused by chemical imbalance that can't be treated without medication? it would be nice if you backed up some of this stuff you''ve been saying.
