I don't disagree with your interpretation of depression, but I do find fault with this statement: > Depression is not lack of happiness. Sadness, melancholy, even misery and pain aren't depression. I'd argue that melancholy, sadness, and misery can all be the essential framework of other types of depression. Just because you don't experience that kind personally doesn't mean that others don't. I suffer from aural migraines that cause temporary blindness. Some people get migraines without the blanking of vision. Even though someone else with a mind-splitting headache doesn't have the classic visual aberrations with it doesn't mean that they aren't having as painful or incapacitating of a migraine as I am.
