Ok, let me start off by saying that I have never personally encountered an emotional situation that affected my life to the degree that this has influenced yours. I can however empathise with the circumstances you face in having to rely almost entirely upon the whim of whatever physician you happen to be seeing at the moment, most of whom are as baffled as the patients they treat, and of course free of the crippling symptoms which can turn everyday activities into almost unbearable tasks. So before I continue on to say what will most likely gather scorn from the masses I would suggest you try Nardil, it's a non selective MAO inhibitor so the dietary changes would be quite severe but it's been shown to succed when others fail (but you'll probably have to push hard to get it nonetheless).

Anyway, onto my somewhat controversial advice... if it's truly that bad and nothing else works then stop courting your brain with endless anti-depressents and mood stabilizers that may or may not work and go strait to drugs that ARE effective. Thats right, the potentially habit forming ones. Unfortunatly this means going from dr. to dr. and tell each one something new until you aquire narcotics i.e. percocet (endorphin systems), d-amphetamines (domaminergic and norepinephrine), and benzodiazipines i.e valium(GABA). Chances are that some combination of the above mentioned should provide some TEMPORARY relief of your depression. You see, the truth is that depression can be overcome by making drastic changes in lifestyle such as exercising more, eating better, socializing more, and most importantly NOT STAGNATING.

The difficulty with depression though is that these things are exactly what it wants us to avoid, thus we must turn to medicine to enable us to push through the dark cloud and emerge on the other side. And although I will undoubtetly draw critisism from all sides for this suggestion (especially for including narcotics) I have seen it done right and have seen it work, if one is careful and uses the window of oppertunity granted in the first few months to incorporate the above mentioned lifestyle changes (essential if embarking on this path) then in a lot of cases one will be able to become independant of the need for ANY medication whatsoever. Well... I guess I'm done, I just thought I ought to mention that if one is not careful and lapses into addiction then you'll turn out much worse than before, so avoid recreational doses and go no longer than 2-3 months.
