I don't think antidepressants actually work....I think it's a way to give some sort of affirmation to the patient that he will be fine IF he takes the pills regularly. It's all about what you believe in. There have been cases where medicine has been proved wrong when they write-off a patient's case as can not be healed, but the patient, just because of his sheer determination and faith, has recovered without the help of modern medicine.
