i just got on line and am so surprised to read your post, i too deal with the same for many years now. i had ECT which seemed to really help with the depression but all to soon brought about really bad PTSD activation so my pdoc stopped treatment. that was April 05 and now i'm going thru a really bad depressive episode. recently heard about the vagus nerve stimulation. Wikimedia.com is a good source of info on this with lots of additional resources. sorry to babble so long it is just so weird you would be talking about same stuff
