I think the media tend to use "depression" as a general term to describe mental illness. The persons who committed suicide may suffer other forms of mental illnesses. There are a great number of different types of mental illnesses, like there are a great number of different types of cancers, neurodegenerative diseases, etc. Instead of using accurate and specific diagnosis like lymphoma, we use a generic term "depression" in these cases. I think it shows both how little we understand the physiological basis of mental illnesses, and the lack of education in society in this regards.
