I would chime in with asking t about dysthymia also. It took my t a year to come to that diagnosis for me.

I am sorry you are dealing with insurance red tape and some poor health care professionals. It may be worth looking into the insurance laws in your state. (Assuming you live in the US?) At some point if refusal to cover things becomes a "quality of life issue" you might have enough sway to get them to cover it. And as someone who just went through an less than acceptable doctor's appointment, I say don't be afraid to complain about your neurologist. It can be scary to call a professional on his/her behaviors and practices, but remember that you deserve the best care you can get.
