Met Life, being clean shaven doesn't mean I'm not depressed

I have been diagnosed with Bipolar Disorder. Previous to this diagnosis, I was diagnosed with Major Depressive Disorder and have been on medication for anxiety/panic attacks since the late 90s. I was out of work previously from 3/27/2013 – 2/11/2014. Only returning to work because all benefits were stopped and had no mponey to support my family. I also have a claim no for a period of time from 7/17/2014 – 2/8/2015 (current claim denied – waiting to appeal). Also returning to work due to income. MetLife has denied all claims I have made for these illnesses. I have been seeing specialists, doctors, and councilers for these issues. I was sent a letter during the 1st claim by their Independent Physician that stated because I was clean shaven and did not want to kill myself or anyone else that I was able to go to work. I have lost cars, been without food and utilities for periods, my credit is ruined, and I owe everyone I know because of MetLife. My current claim was paid for 2 pay periods (4 weeks) and then the rest has been denied. I am at the stage of filing for an appeal. Is there any recourse for getting my lost income?
