I certainly have felt this, and continue to feel anger...a great definition of depression that I heard a long time ago, which I am sure applies to me, is anger turned towards the self. When I'm not angry at the "dis-ease", I'm into full-blown apathy about every aspect of my life. My thinking is that if I just "give-up" then I'm receptive to some changes. Sadly, those changes have not emerged, so I vacillate between apathy and anger...and neither is a good place to be...
