I think I would try and go back to some school at your age. You can do vocational rehab and maybe get some kind of skill where you can set your own hours and be your own boss. You can always file for IU. You can get OPM disability and maybe get schooling. I got OPM easy, but it took over a year to get TDIU. I was 52 years old, so my job future was bleak.
