Injured while active duty AF 1977, placed of TDRL, medical collection judgment

I was injured while serving active duty in the AF in 1977. I was placed on TDRL (Temporary Disability Retirement List) and sent home to work a regular job and receive a 50% comp, while still a member of the USAF. In 1980 they medically retired me. The Veterans Admin, then picked me up. I had worked close to 75 jobs between 1980 and 2003. I had been fired from every one of them due to my memory problems and double vision (up close) caused by being hit by a fire truck while taking Air Force documents to the city's courthouse from my base. I was in a coma for several months and the hospital for nearly a year.

My credit was excellent until I lost my last job in late 2003. In January of 2004 the VA re evaluated me and concluded that my disability had gotten a lot worse, and raised my percentage to 100%. The only income I have is my disability monthly checks. All 3 of my past due bills were taken out while still working and receiving 50% comp. I now have 2 judgements against me and another one I expect to be filed anytime. I can not work, and my disability will never get better. I am "totally and permanent disabled". The judge that handled my judgements told me that I have a case for a "total and permanent disability discharge", but nothing could be done because no action has been taken to garnish my wages or any other action.

I talked to the local Bar Association yesterday and they told me that these debts are "non collectable secured debts". Since I started receiving my 100% compensation my credit has been excellent. It is just the 3 debts that I acquired before my total disability. Is there any way to get these debts removed? My credit scores are 587, 588, and 446. I also can't understand how 2 can be where they are and the other one so low. Any advice for me? I would appreciate any guidance. The bar association also told me that they could never touch my disability income. But if I would like to buy a small house someday, I want to have decent credit. Thank You

all i know is dispute, validate and negotiate the debts and hope
you also have to keep 3 rated lines of 12 months good credit
all that disablitiy stuff is not really credit. I can't help much there.
