Sure it's possible. I think the definitions of words compared to our actual experiences can vary greatly. But either way, I've had similar experiences to many other people that are still trapped in them and I know for a fact that you can do something about it. Even if it's just talking to a friend and asking for a hug.
My point was that your claim that positive thinking or willpower or whatever can cure depression may be far more accurate if you’re talking about the former definition than if you’re talking about the latter definition.
