I think, if we look at individual causes, we might find thousands. But it is easier if we look at levels of our lives, and causes at each level.
First of all, I would not call "situational depression" depression. It is grief. Depression, by definition, is a low feeling that does not have a legitimate situational reason behind it.
It is important to consider:
- physical causes and remedies: sunlight, diet, exercise, supplements
- emotional causes and remedies: unacknowledged feelings, unexpressed feelings, lack of ability to manage feelings, rage turned inward.
- mental (cognitive) causes: Beliefs that one cannot handle one's feeling, beliefs that depression is incurable.
- energetic causes: lack of flow in life
- soul causes: not living one's life purpose
- spiritual causes: living a harmful or self-harmful life, then becoming depressed so as not to do harm.
In my view, genetic causes are less significant, simply because, whether they are present or not, there isn't much we can do about them.
In my experience as a holistic healer, depression is challenging, but can generally be relieved in a few months with holistic treatments and without prescription medication. My own health coach, Dr. Harold Koning (www.mind-bodystrategies.com) has a very good program for this.
