Does anyone have any knowledge about TGSLI, or if there is a program to learn about the process?

Have a question about TGSLI and the process, in 2002 I was severely injured in a mva while on duty ending in a 15 yr fight with the VA to be rated, the TGSLI denied my application because I was never hospitalized long term, being there is no intervention to resolve the problems I have with my right hip I've been through every know treatment for said injury with negative results I also can't locate a time frame, I have roughly 2500 hundred pages of VA records and close to 1000 civilian medical care records that no one is going to sit down and read?
