I had a serious back neck accident in 2007, surgeries in 2008 and back 2010, drop foot and variety of other things... I got pissed off at my doctor

because all he said was that I was depressed and that I didn't want to go back to work.... he discontinued my case, and left me in the lurch, I receive SSDI for almost two years and have just been given Disability from my federal Job because I could not work full time. I asked for my rating and my original doctor refused... now WC are closing my case and I cannot get a "Rating" from any other doctor. I have to 'disprove' their 3rd opinion doctor results, One doctor has refused to take my case, I have tried to go private and yet it seems no doctor will take my case even though there are numerous inconsistencies with what each 2nd opinion Doctor says, the original doctor and a 3rd opinion. How do I proceed, How do I find a doctor who is willing to rate me, or take my case privately and continue to be treated? Otherwise my case for settlement will be closed and I have one year for appeal rights?
