Having been through an eerily similar episode as what you describe (but then as an LGBT employee) I did have an almost perfect paper trail but it still didn't help.
It takes an absolutely insane amount of energy to fight a huge company like this and even if you do everything right the chances are pretty good they'll wear you out first.
Best of luck with your recovery! It's been a really tough few years for me and I can't think of much to say except that I empathize with you and perhaps recommend this book [1] which looking back lists a lot of things that helped me get over it.
