An example from my life is that I'm very hard to bully/persuade to let things go/get to accept bad decisions. Usually, the impetus behind shutting up and going along is that speaking up will have ramifications on one's career. However, I have MS, which means I had to come to terms with possibly losing my career randomly no matter what I say or do. So it's not really something that can be held over me anymore.

I'm way more stubborn post diagnosis because I promise you (whoever you are) are way less scary than the fact that I might wake up and never walk again.

In my life this manifests through a willingness to speak up for those lower on the totem pole, to call people out on being manipulative assholes, and a willingness to take bolder decisions because I've been through worse, so come at me, bro.
