Reality of life...

Today, I could have done without today, gone from yesterday to tomorrow and maybe with today erased, life could be the same, but life's not like that, today one of my best friend found out that he has active Hepatitis, it's heriditary according to him, needless to say I was distraught after hearing this. Since it's active they need to do further blood tests before knowing how serious it is. It is affecting his liver in a bad way and even if it's not progressive it is going to kill him eventually, before his time in this life is up, before he has lived his life fully, before...everything...
He has done so much for so many people already, raising money for refugees, organizing charity events, the list goes on and on and guess what? He is younger than I am...you just can't admire him enough for the selfless life he is living, it is so easy to care about your people, but who cares about the rest of the world?
I'm really lost as of the moment because it's such a sucker punch, I saw him today and he was like always, like nothing had happened, he just completely brushed it off, being brave as usual, finally for himself after spending a lifetime fighting other people's battles. I was trying to be as brave as him, trying to joke...so I guess I have to finally be nice to you now with you dying and all, we both laughed, but not sure what at...I guess at life and how suddenly it can change everything, making everything so much more important than you could ever realize.
I will always be there for him, whenever he needs me, won't be often since he already has like a million people who would do anything for him, but i'll always be here for whatever it's worth and I know he knows that, but there's no recovery from something like this, for him or for me, that's the reality of life...
Everyone should just live happily, happy with what they've got in this life, just be nice to everyone, most of them are fighting a harder battle than yours...
