Depression is a man-made label. The term is taken from the science of weather. The Bible teaches differently and it gives a reason for the affliction. "Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;" .
David welcomed affliction and said of it, "until I was afflicted I went astray".
James said, 'Count it all joy when you face trials of many kinds".
What the world calls depression is a good thing and is purposed to humble and draw out arrogance. The Eternal Almighty hates pride and the cure is humility.
