I can relate to your situation, for years I was diagnosed with schitzophrenia, bi-polar disorder, etc. I've had doctors drug me to the point where I would just lie around and even just piss and shit myself because I couldn't move.
They even went so far as to give me ECT (Electro-Convulsive Therapy) otherwise known as electic shock therapy. None of the meds or treatments seemed to help. While it took a while, what I did was take myself off of ALL of the different meds, and let them get out of your system. This will do 2 things.
Because often what happens is that a doc puts you on a med, then you tell the doc that you are feeling like x since starting that med, so instead of taking you off of that med, doctor adds y to the meds you are taking, then you talk to the doc again, you have these 2 different meds doing different things to your system, and so you tell the doc something else is happening, and he gives you z med.
So you end up on so many medications that it throws your body chemistry way out of wack. Don't just take yourself off the meds, and definitely do not just stop them at once. This is something you need to work through with your doctor. And if your doctor doesn't "Think it's a good idea." Then you know he must be getting a good chunk of change from the big pharmacutical companies to prescribe those meds to you. Remember, the doctor works FOR YOU, YOU (often through insurance) are the one who pays his mortage, and for his golfing "business" trips.
But if the doctor doesn't want to work with you, find a doc who will.
Also, throw out the pre-conceptions of needing to have a name for the illness. Let the doctor treat the symptoms.
And remember if you do want to give a name to your illness, you are not your illness, so a good thing to say to yourself, rather than "I AM Bi-polar" try using "I HAVE an illness called bi-polar disorder"
