Depressed is a reg term for bad feeling. People use it when they feel bad. Might be their bad. I doubt anybody says "I am depressed" with "let's be offensive" in mind. Rather they mean "I feel ****ing bad".

And I am one of the people who don't like the term disease or illness when it comes to troubles on the emotional specter.

And it may be cause English is not my native language, but I am not getting the "not a description" part. Aren't labels used to... uh.... describe a set of symptoms. And how is misusing a term "description"?
