I once went through a major depressive episode, filled with obsessive, irrational thoughts, and anxiety for 6 months. It was pure living h***. Let me tell you, it can and will get better. Make sure your doctor knows how long this has been going on so he/she can make changes. It may mean trying a different antidepressant or something.

I suffer depression on and off, but to a lesser extent now, and since my p-doc doesn't want to prescribe an antidepressant for me right now, I self-medicate with caffeine. As crazy as it sounds, sometimes a stimulant can help soften the angst of depression. Maybe a stimulant would be another thing you could ask your doctor about.

Best wishes of good luck in your search for inner joy and happiness! DO see your doctor about this and don't stop fighting it.
