I read some helpful things from Richard Baxter a while back on this topic... here are some of the sections I remember finding most helpful:

Section 8: Help for those who depressed

Section 9: Duties of friends and relatives of those who are depressed

Section 10: Medical care for those who are depressed

Below section 10 you will find a editorial comment on Baxter's medical views (his knowledge of how the body works was obviously more primitive than our understanding)

Did we ever hear any cry out on their deathbed that they have been too holy, that they have prayed too much, or walked with God too much? – Thomas Watson, The Godly Man’s Picture
