That's a gross misunderstanding of what clinical depression is. If you can trace how you're feeling to being a reaction to something that is a legitimate reason to be upset, THAT'S NOT CLINICAL DEPRESSION. Depression is a physiological issue caused by a neurotransmitter malfunction and no amount of wishful thinking or denying the problem will make it go away. There are techniques you can use to manage the symptoms without medication, but even with medication there is no cure. You can't just tell someone "cheer up", and you can't just will yourself through it, because the chemicals produced by the body interfere with your ability to control your own thought processes, and that's what the medication addresses: it gives you more power to control the part of your body that isn't working right.

Edit: That's not to say that everyone with depression should be on medication. You should always pursue the course of minimum effective treatment. If you are managing your symptoms acceptably well with non-medical techniques, don't demand prescription medication.
