I'm genuinely making an effort to understand how this is relevant to someone with a cancer diagnosis. Sure, dead comes sooner or later, and that's the whole point of why one would feel it sucks and that we're losing, because often cancer means for you, dead came way too early. I have not known anyone with cancer, but I can't help but feel somewhat related as I have a loved one with a mental condition. Although there are techniques such as 'radical acceptance', it's easier said than done, and when it comes from an external party advising you to accept it, it feels invalidating, because they don't know how it feels (even for others with cancer or mental conditions, each person experiences it differently).
