I can do nothing better for a pastor suffering from depression than to point them to the following articles. The only problem is the assumption in these articles that the pastor will be male, and the spouse a wife. But since most ministers I know are such, please read for the terrific insights and statistics within.
Two pastors tell of their journey into depression/burnout and of their steps toward healing. Please read the following articles.
Their wives share the story from their perspective.
Grace and peace to you!
