I have never heard of a doc prescribing opiates for depression and I don't think one ever would.

I am a recovering drug addict and alcoholic so have some experience with opiates. I have to say they are the best anti depressant I have ever taken. However the addiction and withdrawal from them is not at all worth it. You don't have to have an addictive personality to get addicted to opiates.

I would advise the whole world to stay as far away from opiates as possible except for pain management which is what they are for.
