I really can't help too much, but, i find it absolutely crazy, that, men and women fight for our country, risk their lives for our freedom......then, when your down...the same military you so devoted your life to, punches you like a bad employer would. It's discerning that we live in the richest country in the world, however, prefer to give our money to people who don't want to work and buy their own food and medical insurance rather than someone who has a hard time doing the same and has devoted years of service to our cause. I highly respect persons such as yourself....and thank you .... from a fellow citizen, you deserve better.
Don't give up your rights, like liz said, you automatically qualify for SS. You'll also want to register with the MDA and the ALSA. Medicare will likely also step in for you.
I hope things turn out ok, please come back for any support needed. It looks like her sister may be able to help you get thru the ropes of the military medial system. IMO, you are better served going to an ALS clinic rather than the VA. I don't know for sure, but i think Medicare will pay for the clinic and the MDA should pick up the balance of the bills? I could be wrong, but taht's what i was told.
best of luck
