So, you are saying that depression can simply be a certain outlook someone has regardless of their emotional/mood state? I personally do not agree with this. I think that the only way to perceive any negative quality in your life is through your negative moods/emotions.
I'm saying depression is a clinical illness, like Bipolar Disorder or Schizophrenia. You don't treat them by "changing your mood". Mental illness is not - and should not be - a matter of "personal opinion". You are spreading medical mis-information that could be harmful to others.
Again, I never said that it is a simple matter of changing your mood. Yes, I do think that depression is a negative mood/emotional state. But you are right when you say that it is not as easy as thinking happy thoughts or going outside to try to change your mood.
Which, in turn, is a depressed mood (a negative mood state). It's different than a normal mood since depression is a negative mood state that tends to be chronic and very difficult to recover from.
No, it is not. It is a chemical imbalance. This is my time to step back, and hope that the Mods move this is a more appropriate forum.
