Most evidence is that antidepressants and other forms of therapy (particularly CBT) go together like peanut butter and jelly.

Depressant drugs such as Xanax or Klonopin on the other hand open up ion channels in your neurons that let the electrical charge drain out. You get fast and often complete relief from anxiety but learning and memory is impaired.

People who use benzodiazepines for a long time seem to grow older but not grow up, you see them and they still have the same conversation that they had with you ten years ago, they just don't seem to move on the way that most people do.

That's not true about antidepressants.
