My Darkness. How good and evil battle for my soul on a daily basis.

I fight the darkness,everyday.  I suffer from depression ever since I was a pre-teen. I've been to therapists, psychologists and taken medication.  But the darkness never fully leaves.  When the darkness envelops me, I'm unbearable.  I argue for no reason, I yell and scream, I've even broken things and thrown things.  But worse than that the darkness has been responsible for the near total collapse of my marriage.  And when my dream girl couldn't take it any longer and didn't want to experience a nasty custody battle, she resorted to things in order to survive.  These "things" have broken my heart and  I have had trouble coping.  Anger and resentment aren't the answers they only feed the darkness.
