Having been on anti-depressants myself, which really do take a while to work, and then gradually, I can also very much recommend the "Idiot's guide to Cognitive behavioral therapy". There is insight in this book as to why and how people get depressed - better than meds imo, as understanding gives you power.
Good luck -
