I found these two articles that mention that taking SSRI for depression can actually make the depression worse.
Is it true? Can Tardive Dysphoria (delayed depression) be caused by SSRI?
They seem pretty convincing and I can't find anything against it but if it's true, it basically means that depression treatment is going back to the 60's before SSRI were invented (or it should even though that's billions in losses for big pharma).
