Doug, my prayers and thoughts go out to you. Knowing extremely well what you are dealing with first hand, sometimes, no all the time, you need to seek some other help via medication or theraphy. Not saying this in a critical way, but as Dock Nock said, a lot of this can be caused by a sever imbalance in blood issues. It's not just your brain telling you you are depressed. Please go and see a doctor. Believe it or not, sometimes they can work wonders, never a miracle, that is God's work.
