I was just denied TDIU for anxiety and depression that I am rated at 70%. The letter said that the c&p doctor did not say that I am not able to work but do have symptoms to continue my 70% rating. On my regular monthly appointment at the VA i told my phychiatrist that I had applied and got denied and she said with my records she didn't understand why, so she made me a formal letter saying I was unemployable even for sedentary work and the my condition was unlikely to improve. I just did a request to reopen my claim with that letter and a letter from my wife and ex co-worker. My question is how strong is that letter from my VA doctor for a TDIU approval.
