I'm not sure that making depression out to be an enemy or beast, or a monster is the correct path. That creates more conflict in your mind.

What if depression is simply your brain's misguided attempt to protect yourself from the ills in life? What if it is just a response to the reality that you are living a life that is detrimental and ignoring your needs that aren't being met? What if depression is that inner voice screaming, "Please listen to me!"?
