My depression is only the tip of the iceberg.  It is only an indicator that there are too many things below the surface I am feeling helpless about and I have to examine those things, reconcile what I can and go on from there.  Everyone has struggles and so much control of their life.  What do I have a little more control of?  And change what I can to whatever degree.  Depression does not really usually stem from one cause but really comes from an accumulation of things you have lost control of or at least feel that way.  Grabbing back some of the control gradually should lift the depression.  At least, I hope so in my case.
