Long Term Disability Claim Denied by Prudential regarding aniexty disorder. Want to appeal so I can get medical treament by Drs.

I have been with my employer for 20 years and had stellar performance for all 20 years. In Nov 2012, I accepted a new position within the company and discussed with management that the job was not a good fit for me. After that conversation, starting in Jan 2013, my manager had been bullying and harassing me in the workplace. She is black and I am white....not that this makes any difference, but it may. After all the harassment, bullying and abuse, on 3/21/13 I asked for a medical leave of absence due to my emotional and physical health were being affected. On 3/22/13, I had a car accident and continue to have residual effects with my left shoulder and back. I feel that my mental state may have contributed to the car accident. On 3/26/13, I contacted my HR dept to report the harassment and bullying issues surrounding my supervisor. Nothing was done to remedy the situation and I requested a job/dept transfer. However, JP Morgan Chase & Co does not have anyway to assist an employee with this type of transfer, so my request was denied. Not sure what legal recourse, if any I have. My FMLA job protection ran out on 7/18/13, the company has filled my position. My short term disability ran out on 9/18/13. Also, I applied for long term disability through Prudential on 8/15/13 and the claim was denied as of 9/27/13. Now, I'm needing assistance in appealing the long term disabilities decision.
