Yeah, Juliana, "Darkness Visible" is good -- I have it too, & I highly recommend it, ouch.
I have a ton of self-help books.....but they are packed away @ the moment.....can't think of many off hand......perhaps "Listening to Prozac"....sorry, can't recall author off-hand.
Maybe go to local bookstore or library & peruse self-help or psych section?
