blueglass...i'm not familiar with the illness either, but I believe you are right to think there is something more than depression going on. It seems that most people with depression really do have some other diagnosis that fuels the depression, but since most people only run to a general physician they are never correctly diagnosed.
There are so many different diagnosis' out there that are so similar to each other that I'd venture to bet that half or more of us have been misdiagnosed or not fully diagnosed (meaning there are more than one illnesses to contend with).
In your 10 years of depression...have you ever thought about or tried ECT? You might take a look at it and learn about it b/c there are some depressives who find relief in that kind of therapy. If I had insurance right now...well, I would have tried it along time ago.
I can relate to many of the symptoms you guys have listed....but that's the problem, I think....so many people can relate to SO many symptoms from so many different mental illnesses. I wish someone would totally re-define the different types of mental illnesses to make them easier to diagnose....right now...everything just seems so wishy-washy. Does that make sense?
Hugs and best of luck....please keep us posted as to how things are going and if you find something that really helps.
